Made it through the account migration. But later lost my account after some hacker compromised my microsoft account. Microsoft kindly let me know about some unauthorized access, and then promptly deleted the account :) .

That was the last straw from Microsoft for me. Never again.

Was it really Microsoft or was it Mojang? There were two account transitions, and in my experience, most customers use Microsofts name, but are complaining about the first (Mojang, not Microsoft) transition.

I have lots of problems with Microsoft but the Minecraft transition was handled very responsibly.
