Having problems with pvp and co-op

I don’t know if anyone else is having this problem but everytime I go to play co-op or pvp the game locks up when I enter the arena. Now I can close the game and come back and everything g is fine or close the game before hangd and open and the first time I play I’m fine. I’m running Android 7.1.1 with 16gb rom and 2gb ram and a 32 gb class 10 sdcard wonits more than enough to play this game. Any suggestions?I’ve tried clearing the cache,wiping phone, uninstalled and reinstalled the game and still the same problem. Thanks
