I own multiple accounts with one of them being Mojang and the others being Microsoft. I have found an issue which has happened to me and multiple other people I know. Occasionally every couple days or so the minecraft launcher will forget my microsoft accounts own the game and will say i can only play the demo. This happens with all of them at the same time. To fix this issue all i have to do is remove and relog into my ms accounts in the launcher so im able to use them again. This also happens when i change the skin/name of one of these accounts and suddenly I all of these ms accounts forget that i own the game and i have to relog for all of them. This doesn't happen with my Mojang account. As it happens randomly every few days or so it gets very frustrating to always re add these accounts just if i want to play on a different one. Hope you can help me with this issue, thanks
