I successfully migrated my Mojang account to a Microsoft account and have the migration confirmation email as proof. However, when I open the minecraft launcher, it says I don't own Minecraft Java Edition and that I can only play the Demo. I've owned Minecraft Java Edition before the migration and therefore, I should be able to play Minecraft after the migration.
When I sign in to the minecraft launcher with the microsoft account that this confirmation email was sent to, it only says I can play the Mincraft demoI've seen many different users with the same issue and there have been no reasonable fixes to this issue. It would be greatly appreciated if a fix could be found especially since I want to be able to play Minecraft.
