Minecraft Account after migration isn't working and it says i have to buy the game even...

No, it wouldn't be there anyway, lemme explain. I bought Minecraft back in 2012, this was way before it was even considered that Mojang would migrate accounts to you, back then, to get the game, you had to buy this special card and Walmart for 30 dollars then sign up for Minecraft after the payment was made. I migrated my account last night and after the migration completed, when I signed on it was giving me the option to play the demo, and telling me that I had to buy it again on their website to get the full experience.

Hi, I’m signed in under email which was used for my mojang account(this email)And I also migrated from mojang account to this email I’m using to sign in.

Hi, I hope you're doing great out there. I am an Independent advisor and I am here to help you with your concern.

This may mean that you're signed in under the wrong Microsoft account.

Please sign in on your launcher using all Microsoft accounts that you own, Lenka.

I appreciate you checking and to confirm, you're seeing just a demo mode for Minecraft Java Edition? If yes, you may need to check this link as well from Mojang:

The exact same problem happened to me too. I migrated my Minecraft account to Microsoft, worked fine for a while until just today, now it says I don't own the game, even on the website. Makes no sense, I sure hope this isn't some purposeful treachery on their part and gets fixed soon.
