Got it. Thank you so much!
Hi, my issue is in PC with the windows 10 edition, and ill try to explain it as clear as I can: First i joined the beta in Xbox Insider and it worked, the beta was installed and I could try it in-game. The issue comes when Xbox Insider still shows me to join the beta even though im already in, and when i press the "join" button it shows "(pending)" for a while and then "join" again. Its something like Xbox Insider doesnt detect that the game is already in the beta version, and therefore i cant uninstall the beta from Insider because i didnt even joined the beta, and that may be the cause of all this thing.
I already tried the steps in minecraft feedback with no result and yes, after i uninstalled and reinstalled Minecraft it was still in the beta version.
Sorry if the explanation is a bit messy, and thanks for your time.
Ive just had this same issue and spent over 3 hours trying to fix it with all the current "solutions" for this problem with no result. I need help, please
Happy to see your warning Auldrick, it worked for me as well! Feeling dumbish after the long time I spent trying to solve this issue at my own for it to be now fixed by itself, but glad that its actually over so I can finally leave the beta version.
Thank you!
