Not able to unenrol from minecraft beta

If you're enrolled in the Minecraft beta you need to unenroll from the same (you can unenroll from the Xbox insider app)

You would opt into the Minecraft Beta via the Xbox Insiders App. Unenroll your device, via the Xbox Insiders App, from that beta test and it will START the process to remove you from the beta. This can take sometime and might require the updates to cycle
through the next release, catching the full release up to the beta versioning before you are fully unenrolled and able to access the full release again.

Hello Camellachee,

Thank you for posting here on the Xbox forums. Are one of you guys enrolled in the Minecraft Beta? The outdated client issues means that either one of you guys is not fully updated in Minecraft, or one of you are in the Minecraft Beta. To unenroll from the
beta, you would launch the Xbox insider hub to navigate to Minecraft from there and then select unenroll or "Leave this preview."

Hello!

I believe it may be because you have the Beta Preview version of Minecraft on your Xbox! You are able to unenroll the Beta version of Minecraft through the Xbox Insider Hub app.

Follow this if you need:

Insider Content > Minecraft > Manage > Unenroll

You will need to uninstall and reinstall the game for this to take effect.

Hope this helps!

NOTE: Keep in mind that any worlds you have played as you were on the Beta version will be unplayable with the earlier version.

If you are enrolled in the beta, you have likely been “updated” to the beta. Betas do not have access to Realms.

If you wish to unenroll from the beta and reinstall the normal version you can do so via the Xbox Insider Hub.

1. Xbox Insider Hub → Insider Content → Minecraft → Manage → Unenroll
2. Uninstall Minecraft
3. Wait for the system to process the unenrollment (approx. 20 minutes, up to several hours)
   
4. Download & reinstall Minecraft

If the beta continues to download after unenrolling, you may need to allow additional time for the system to process the unenrollment. You may also
power cycle the console before attempting to reinstall the game.
