As you can see in the picture, I'm asked to buy minecraft, but I already have it. Even the days before I could play it normally, strangely enough not anymore? Does anyone know how to fix this?
Are you signed in with the correct Microsoft account?
Simply register and buy. Already had the problem on a new device. Go to the store where you bought Minecraft and log in with the account you used to buy Minecraft.
Do you work in the microsoft store? If yes, then yes
Register again - and if that doesn't work, then play Minecraft Java Edition. Haha.
