Not aloud to change country on the App Store!

So I’ve only just notice that my App Store is in a different language but only for reviews and then I noticed that the £ logo is now some weird currency that I have never seen in my life! So I go to change the country thinking it must be a mistake as it wasn’t like this last month and it tells me I can’t change it without cancling my Apple Music which I wasn’t overly happy about but I cancled it just to change it just to find out I still have to wait for my month I’ve paid for to run out before being able to change the country! I’ve had Apple Music for about a year now so if you can’t change the country with an Apple Music subscription how come last month my App Store was English and all of a sudden it’s another country! Is this actually a joke I won’t be re subscribing to Apple Music now may as well use Spotify or Amazon so it doesn’t mess with my whole phone!
