@MojangSupport ever since I migrated my account, i am unable to play full minecraft java, only the demo despite the fact i have owned the game for years

If you're only seeing the demo after migrating, this usually means you're logged in with the wrong account. Please try logging in with any other emails you may have used during migration. ^NS

only two emails were involved in my migration process - an outlook account and a gmail account - and logging in with either of those has the same 'play demo' prompt
