Hello Keoni Liang,
It looks like the lock is sitting on your Microsoft/Xbox account itself. The thing is, that lock only shows up in a few specific account situations, and the fix path depends on which one you're in.
Could you share a bit more so I can point you at the right one:
- How old are you, and is your Microsoft account birthdate set correctly?
- Is your account part of a Microsoft Family group (e.g., managed by a parent), or standalone?
- Which country is the account registered in? (UK has a separate age-verification requirement that blocks Minecraft chat until verified.)
- Did anything change recently on the account side — birthdate edit, left/joined a family group, age verification prompt?
Once I know which bucket you're in, the toggles to flip could be straightforward.
