When I try to log in with my Microsoft account, I did the migration a couple of weeks ago. But today I think a new update came in for the launcher, so it is problem that I have a bug with the synchronization between accounts, since an error occurs; "Failed to login". I am confused, I have my account in order, so it is possible for me to access the web through the Microsoft account. Please solve it or notify me of news. Thanks.
