Minecraft automatically going into beta on Chromebook versus.

So yesterday morning I was playing Minecraft fine and then randomly during the day I logged into Minecraft for me to be in beta and it doesn't seem like I can do anything to get out of it. I'm worried I won't get the realm I paid for back because I can't access it. it's been a day and it's still not fixed. (I've tried restarting, logged in and out, uninstalled reinstated. I don't know what to do)
