It's so annoying trying to swipe those notices away and instead start loading their match. Happens all the time, I really hate the flurry of notices on association days. I don't need 5 " Thank you" notifications in a row, I'm concentrating!

It's bad because they can pop up and prevent actions in the lower section of the screen. Raise your hand if you've ever tried swapping a defender and instead get taken to your association mates match
