Can only play Minecraft Demo after Migrating Mojang Account

I am logging into Minecraft Java Edition with the Microsoft account that I migrated my Mojang account to, and instead of being a full/paid version of Minecraft, it is only offering me to play the Minecraft "demo" version.

Also experiencing the same thing. I was able to play minecraft just this morning with the same account. Then when I tried logging in tonight, it says that I can only play the demo version. This only happened after I migrated to a microsoft account the other day. Get this fixed, microsoft. If you;re going to force us to migrate from Mojang accounts, then make sure the foundation is properly laid!

How did you migrate on the website, i've been searching for hours how to fix and i can't figure it out

thank you

Hey, I had the same issue. If you are using a Mac, try using a different browser than safari when you migrate your account.

So if that helps, I have feedbacks about it.
I've had a hard time understanding my mistake, but here it is :

I began migrating my account on the specialized website, then I had to log in my microsoft account.
BUT I was tired and forgot the password, so I began to reset it, wich means that once I was done with it, the website redirected me to the exit with a "thanks, it's all good" message.
So I wasn't paying attention and thought I had successfully migrated my account. But obviously, I should have gone back and typed my passord to validate the migration.
So yeah, make sure you did migrate your account. May be the issue.
