Apple Arcade is not working

I have an Apple One trial subscription (on one month), but Apple Arcade is not working on my iPhone. On others Apple device I can’t test this. My iPad is very old for Apple Arcade.

When I open App Store —> Apple Arcade and try download games, Text about an offer to buy Apple Arcade appears, but Apple Arcade included with Apple One subscription.

Games that I installed when I had only Apple Arcade is working, but now I can’t install others Apple Arcade games.

sorry for my english :) I live in russia
