do note i found something it might only work for me or for everyone
so it is like this the first time after logging in i get 1 ranked ease but after i dont but i found thaat if u go out of the arena interface and walk around a bit or switch screens a few times and go back i get a fight as soon as i click in most cases and 4 min longest ( got 1 4 min 3-4 2 min a few 1 min and around 34 30 sec other than that i got a fight as soon as i clicked on ranked)
o yea and another person found that if the loading circle only appears 1 time u wont get a fight if it appears 2 times u should get 1 in less than 10 min so try a bit it should work........
