i’m on console. every time i try to login it says i need to buy 3 packs of tp medals.

Thanks for the update mate

If the Microsoft account is the same that you used to migrate your Mojang account, I think could be a problem with the license, I can advise you contact Mojang support with proof of purchase. Would be better if you use the transaction ID given by them when you got the game

In that way they can track the license easily

Yes, this is Minecraft: Java Edition but for Bedrock Edition its okay, and yes did tried all things that I described and tried to log out and log back in to Microsoft store and Xbox but it didn't work and I didn't purchased the game after December 1 2020
