I have sent out a bug report at mojang.com yesterday. https://bugs.mojang.com/projects/MCPE/issues/MCPE-61661?filter=allopenissues
However, today I told some of my friends my issues. And one of them said they had the same problem and the way to fix it is to use another microsoft account.
And first of all, whenever i sign into Minecraft, it automatically signs me into my current one and then just freezes. And the second problem is that, if i quit this account and go to another one, all my data will be lost from MCPE servers. For example,
on The Hive I bought the Hive + rank and a few other things. It cost about 13$ total.
I really do not wanna loose my rank and my stats on the server and im hopeless right now. :(
If anyone can help, plz do.... I need help to save my account.
