It’s been two times now that my game has crashed mid-match after the latest update.
I’m on a 4S. I really hope this doesn’t keep me from the strong finish I was on my way towards in The Hunt. 
Also, the characters keep their damage from the match I was in the middle of when it crashed!!
SO FRUSTRATING.
Close all open apps, and restart your phone. That quite often helps.
Since the update I can’t connect to the servers on either my phone or PC, please fix this
Ran into this at the start of a match as well on my Android tablet.
As mentioned, it counts as a loss (probably to discourage force stopping the app), which really stinks during the tournament.
