(Minecraft) Mojang Account Migration Issues. Launcher Says I Don't Own Game Anymore

Then for account issues you should contact Mojang directly!

That’s the first thing I did. They told me to contact Microsoft, and Microsoft led me here.

Hi there welcome to the community forum! Christopher here, an Xbox fan just like you and has been on Xbox for years already. I would really love to make your day by helping you out. Had a similar problem, follow these steps !

If you have any other Launcher on your computer other than the one found on Mojang's official website you must first do the following:
1 - Delete the Launchers that exist on your computer that are not official Mojang;
2 - Restart your computer;
3 - Download the original software again and install:

If you don't have another Launcher on your computer or have already deleted:
1 - Open Minecraft Laucher;
2 - If you are already logged in, click on your image and Gamertag in the upper left corner of the screen and then on "Logout";
3 - If you are already logged out or not logged in to your account, delete all accounts registered in Launcher by clicking on the "X" next to each account;
4 - In Minecraft Launcher, enter the email and password of your Microsoft account!

Sadly this didn't help. The problem I think is according to my account, I don't own Minecraft at all anymore, even though I do

I have this exact same issue. Even though I migrated my account, it seems to think I don't own Minecraft. I can play Minecraft on the old launcher (logged into my Microsoft account) as it seems to recognise that I own the game there. Its only the new launcher that is having the issue and the Mojang website.

If you still have the old launcher installed maybe give it a go as it still works for me.
