minecraft isnt going back to non beta version when i unenroll from beta program

According to https://minecraft.gamepedia.com/Bedrock_Edition_beta_1.13.0.1 it seems you opted in to recieve BETA updates to Minecraft.

As Beta versions are test versions and might contain unstable code, public servers do not update to Beta versions.

So if you wish to use public servers, make sure you only use non-Beta versions of Minecraft. If necessary, un-enroll from the Minecraft Insider Beta program, and wait until the next official update, or uninstall and re-download the latest public non-beta
version of Minecraft.

If you are in the Insider Program and receiving beta software you can safely revert to the last wide release (non beta) software by unenrolling from the program by following these steps https://news.xbox.com/en-us/2018/02/12/unenroll-old-unused-devices-xbox-insider-program/

If you are not in the Insider Program please try out the procedure Echo4Ent has posted.

Hello!

If you opted into the Minecraft Beta, then you removed yourself from the beta program, your game will still stay on the latest Beta version. You would need to uninstall and reinstall the game to get on the latest full (non beta) release.

If you unenroll, you will be removed from the Beta and placed back into the Public version....

Hello Kanji,

Thanks for posting here on the Xbox forums. We would like to check and see if this is a console, or an account issue. Does this happen when other accounts play Minecraft on your Xbox? Do you have a second Xbox to test out by any chance?

Also, were you a part of the Minecraft beta, or the Xbox preview program?

Hi.

I dont have a second xbox to try it out unfortunately.

But the friends I play with on minecraft dont have this issue and we all play on the same map ( the map was created on my xbox. I am host).

I have my sons and nephews account on my xbox will i try play on their account?

Also I was apart of the Xbox Preview program in Alpha. I left this about 3 months ago but stayed on the minecraft Beta program. Then about 3 weeks ago when i realised i couldn't play with a friend that wasn't on the beta programme i unenrolled from it.

I am now on the non beta build.

This is not the Xbox one versions of minecraft it's the version just called "Minecraft" on the store
