Hi,

Trying to create a declarative Copilot chat agent. Setup so far:

  1. Bot service with Teams + M365 channels

User-assigned identity added

Teams app created via Teams Dev Portal

App is published and visible in Copilot

Backend receives messages and sends responses

Tested both BotBuilder 4.16.2 and Teams-AI 1.7.0

Tried all combinations: send_activities, continue_conversation, text/cards/indicators, proactive, etc.

Problem:

Copilot shows typing for 1–5s, then nothing

Switching chats and returning shows the message

Works fine in standard Teams chat (non-Copilot)

Anyone know how responses should be sent so they show immediately in Copilot chat?Trying to create a declarative Copilot chat agent. Setup so far:

    Hello @Karlis R

    Thanks for reaching out. The issue you're experiencing, where the Copilot chat agent shows typing but doesn't display the message immediately, is a known problem. The product team is aware and working on a fix. As a temporary workaround, you can switch to another chat and then return to the Copilot chat to refresh and display the message. For more details, you can refer to the known issues documentation on the Microsoft website.
