Ekko ult and camera mode

every 2nd or 3rd ult freezes the camera on me and nothing but reconnecting can help? that little button near the map doesn't work, i pressed it in 2 games now multiple times and does not work, pressing "y" as my teammates told me - doesn't work, i have to reconnect to the game every 6-7 mins, it's annoying and it really doesn't help me win games. can someone tell me a way to unblock the cam or something...
