Migrated Microsoft Account at Demo Mode

I have the exact problem after migrating my account to Microsoft. Now my launcher says that I can only play in the demo version. As you already know, after the migration, you can't log in via the Mojang account anymore, so it means that I went back and logged in via my Microsoft account.

One thing to mention though is I did my transaction via my first email address which obviously was linked to my Mojang account back then. However, I had no Microsoft account with that email address, and I migrated using my second email address which had a Microsoft account linked with it. I think the problem is somehow related to this. Or that Microsoft has been blocked Xbox accounts for Iranian IPs.

I've been talking to one of the agents in customer support within the past week to solve the problem. But they finally referred me here. Please don't refer me back to the customer support services. Thanks! 

i literally used the same exact email for mojang and microsoft and is at demo but i still can play but i can't play at servers

This is actually still a duplicate of MCL-16570 regardless of if you're using a Mojang or Microsoft account.

Please read the full mod note on that report and contact Mojang Studios if the issue persists after trying the steps there

Thanks for your reply @Greymagic27. I've read the moderator note and although the hyperlink in the 7th step does not show anything to me (as I've shown in the attachments of this comment), I've done the steps mentioned and I'm still unable to fully play the game.

Also, it seems that this issue and all its duplicates are being tagged as "resolved". To my knowledge, this issue has not been resolved since I'm still faced with this problem after 2 weeks of migration. Please don't tag issues falsely. Thanks.
