Issue with Document Intelligence Studio and F0 (Free Tier) Resource

Hi all,

I’ve recently started experiencing an issue with Azure Document Intelligence Studio that wasn’t occurring before (this setup has been working fine for ~1.5 years).

Scenario:

  • I have a valid Azure subscription under the correct directory.
  • I have two Form Recognizer (Document Intelligence) resources:
    • One F0 (Free tier) 2 page or less
    • One S0 (Standard paid tier) process few pdf reports each with +3 pages long
  • Both are in the same subscription, same region, and same directory.

Problem:

  • When I use the S0 resource, everything works as expected in Document Intelligence Studio.
  • When I try to use the F0 resource, I get the following error:

"You don't have an Azure subscription under your current directory..."

This is misleading, as:

  • The subscription clearly exists
  • The S0 resource works fine in the same environment

Question:

  • Has support for F0 resources in Document Intelligence Studio been limited or changed recently?
  • Is this expected behavior, or a bug?

Would appreciate any clarification or official guidance.

Best Regards

Hello Anis Elosta,

Greetings! Thanks for raising this question in Q&A forum.

Really appreciate the detailed description of your setup — it makes it much easier to pinpoint exactly what is happening here. The good news is this is not a bug, and your subscription and directory are completely fine. Let me explain what is actually going on.

The error message "You don't have an Azure subscription under your current directory" is unfortunately a misleading error message from Document Intelligence Studio. The real reason it appears when using the F0 resource is almost certainly a mismatch between what the F0 tier supports and what your documents or projects require. Since this setup worked fine for 1.5 years and the S0 resource still works perfectly, the subscription and directory are not the problem at all.

Here is a clear breakdown of what is happening and how to fix it:

Understanding the F0 vs S0 limits

The F0 (Free tier) resource has strict built-in limits that never change regardless of how long you have used it. These are hard platform limits and not something that can be configured or unlocked. The key ones to know are:

  • Maximum of 2 pages per document
  • Maximum file size of 4 MB
  • Limited transactions per month

The S0 (Standard tier) has none of these page restrictions, which is why it continues to work without any issues.

Step 1 — Confirm which resource is selected in Document Intelligence Studio

Sometimes Studio does not automatically switch between resources when you navigate between projects.

  • Open Document Intelligence Studio at https://documentintelligence.ai.azure.com
  • Click on the Settings icon (gear) in the top right corner.
  • Go to Resources and confirm which resource is currently active.
  • If it shows the F0 resource, try switching to the S0 resource and see if the error goes away.

Step 2 — Check the document you are trying to process with F0

If you specifically want to use the F0 resource, ensure the document you are testing with meets all F0 requirements before submitting.

  • The document must be 2 pages or fewer.
  • The file size must be under 4 MB.
  • Supported formats are PDF, JPEG, PNG, BMP, TIFF, and HEIF.

If your document exceeds either of these limits, the Studio will throw an error — and in some cases that error surfaces as the misleading subscription message.

Step 3 — Clear your browser cache and sign back in

Since you mentioned this issue appeared recently after 1.5 years of working fine, a stale browser session or cached token could be causing the Studio to lose track of your subscription context for the F0 resource specifically.

  • Clear your browser cache and cookies completely.
  • Close the browser and reopen it.
  • Navigate to https://documentintelligence.ai.azure.com and sign in fresh.
  • Try selecting the F0 resource again under Settings and test with a small 1-page document.

Step 4 — Try using an InPrivate or Incognito browser window

  • Open a new InPrivate (Edge) or Incognito (Chrome) window.
  • Go to the Studio and sign in with your Azure account.
  • Select the F0 resource and test again.

This rules out any browser extension or cached credential issue.

Step 5 — If the error persists even with small documents, raise a support request

If after following the above steps you are still seeing the error with a document that is 2 pages or fewer and under 4 MB, this could be a genuine service-side issue specific to your F0 resource.

  • Go to the Azure Portal and open your F0 Document Intelligence resource.
  • Click New Support Request from the left menu.
  • Set the issue type to Technical and describe the exact error, your setup, and the steps you have already tried.
  • In the meantime, continue using your S0 resource as it is working correctly.

To summarise the misleading "no subscription" error from Studio is almost certainly being triggered by the F0 resource's 2-page limit being exceeded, or a stale browser session. Your subscription and directory are perfectly fine. Use S0 for multi-page documents and reserve F0 only for small 1-2 page test documents.

If this answer helps you kindly accept the answer which will help others who have similar questions.

Best Regards,

Jerald Felix.

    This behavior is expected for F0 resources in Document Intelligence Studio when working with documents longer than two pages.

    Key points from current behavior and documentation:

    1. F0 (free-tier) limitations
      • For free-tier (F0) Document Intelligence resources, only the first two pages of a document are analyzed, regardless of whether the request is made via Document Intelligence Studio, REST API, or client libraries.
      • To analyze all pages in a document, a paid (S0) resource must be used.
      • In Document Intelligence Studio, the active resource and its pricing tier can be checked and changed via Settings → Resources.
    2. Impact on Document Intelligence Studio
      • Studio fully supports F0 resources, but they are constrained to the first two pages and smaller file sizes (4 MB limit) compared to S0.
      • If a workflow or project in Studio expects to process more than two pages, or relies on capabilities effectively requiring S0 (for example, processing full multi-page reports), using F0 can lead to failures or misleading errors, even if the subscription and directory are valid.
    3. Recommended action
      • For any scenario where more than two pages must be processed, continue to use the S0 resource in Studio.
      • If F0 is needed only for quick tests, ensure that:
        • Documents are ≤ 2 pages and ≤ 4 MB.
        • The correct resource is selected under Settings → Resources in Studio.
      • If the error persists even with a small (≤ 2-page) document and correct resource selection, treat it as a service-side issue and use the S0 resource as a workaround while raising a support request via the Azure portal.

    There is no indication in the current documentation that F0 support in Document Intelligence Studio has been removed; rather, F0 is explicitly documented as limited to the first two pages and smaller file sizes, while S0 is required for full multi-page processing.
