I have this problem since 2 month ago and this is so annoying. Because i can't play in server, i can't open marketplace, i can't open achievements, i can't buy minecoin, i can't make a realm. And this is my 6th time i got the bug. The first appereance of this bug is in my old account, i try to solve it by relog from my xbox account. But when i try
to log in back it say that my email or password is incorect, im 100% sure that my email and password is correct but it keep saying that isn't. So after many try my account got locked because it think there is someone else try to log in with my account. So after that i decide to make a new account, but yeah it got the same bug so i try to relog from my xbox account again and it say the same thing. So i make a new account again and keep looping and looping. And here i am with my 6th account got the same bug again. But now i won't log out from my xbox account because i know what will happen, instead i report to you guys. I don't know how this bug can happen, but it keep happening after 1 week i create a new account.

So i hope that you guys can fix this bug, so i can play like normal again.
