A few weeks ago I migrated my Mojang account. Since then I have not been able to play Minecraft because when I log in with my Migrated account it says I do not own Minecraft. I also can no longer sign in with my Mojang account confirming that the Migration process did begin. It would appear that other people are having these same issues. I have seen people complain about this issue on the r/minecraft reddit as well as reviews on the Minecraft launcher available in the Microsoft store. This is an issue that needs to be seriously resolved. People, including me, are loosing accounts that have had Minecraft for years and making us pay again for Microsoft's own mistakes is insane.
