Changing Country/Region | Apple Music & App Store

Hi!

I accidentally switched regions in App Store from Bulgaria to United States. I tried to switch it back to Bulgaria as it has always been but I can't because I have to cancel my Apple Music subscription. I understand why it needs to be cancelled and I did cancelled it. (Please, have in mind that my subscription was originally made in Bulgaria and I use my phone in that exact region.)

The problem is that my subscription expires at the end of the month and right now I am not able to listen to my music! The following massage pops up whenever I try to play ANY song: "This Apple ID is only valid for use in the Bulgarian Store". So I'm currently stuck in the US store without being able to listen to music I HAVE ALREADY PAID FOR.

What's more, I am not able to download ANY apps from the App Store. It's a total mess.

Please, give me some piece of advice. What should I do? Do I wait for my Apple Music subscription to expire and lose all my playlists? Why can't I download any apps right now?

This is a simple mistake I made and it should be reversible! It is very disappointing that I have to wait for my subscription to expire so that I could change stores without listening to music until the expiration date.

Thank you!
