Using nnon beta while enrolled in the beta Minecraft program.

Thanks, I was afraid of that. I wonder what becomes of worlds made in the beta if I opt out. Also, sorry for the bad formatting, I don't know how to operate the controls here.

According to what's mentioned in the link below (section: Essential information before participating in a Minecraft Beta), you can't switch back and forth between the two programs. You can find more information about this in the following link :

I am guessing your friend is enrolled into the beta for Minecraft through the xbox insider program

Hey Merry,

I can only give beta forum access to the profile that enrolled in the beta program.

With the Beta dashboard on your console, there isn't a way to get it off or to remove you from the program.

If you can let us know the Gamertag on your console that is enrolled in the beta, we can look into getting that profile access to the beta forums.

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.
