Bugs in Alliance Battles and Friendship Requests

The alliance fights are 80% unplayable. Requests do not work. No reaction if I accept a request. This has been the case since version 1.8. It affects almost all 50 players in the alliance. Nothing happens or there is an error message.
When I make a friend request, I always get the error message: “The friend request could not be completed. Please try again.”
For me with iPhone X and latest iOS.

Hey BuffiBuffke, it’s possible that the request might have expired, usually restarting your game should refresh it.

However, could you reach out to our support team here at support+forums@ludia.com with your support key so our team can take a closer look at your account? Thanks!

I start the game and also my iPhone several times a day because of these bugs. Unfortunately this doesn’t help.
