Problem with Apple Arcade on my AppleTV

Hallo. I've subscribed for Apple Arcade a few months ago, using region of Croatia, since there was no available Serbia (my home country) as a region. However, during May Serbia was officially introduced as possible region and I changed it on App Store. Everything goes fine all across my devices, however on Apple TV it is not possible to download new games, because my region is still Croatia....

Would you please help me on this topic.
