Hello! I recently Migrated my Mojang account into a Microsoft Account and once I have logged in to my migrated account, it acted as if I have not bought Minecraft I have tried several solutions from the internet but non of them seemed to work. Is there any way of fixing this problem or is there any way you could help me? Thank you. 

(It only displayed the Demo version and the pop up to purchase Minecraft was at the side of the launcher)
