Post maintenance issues?

So far this morning the app has closed on me four times right in the middle of an arena fight. This has occurred on both my phone and tablet. Is anyone else experiencing issues?

This game keeps crashing with a higher frequency for me. The graphics get these weird black boxes along with other glitches and the game just crashes.

It happens a lot for me in alliance quest which is frustrating because when the game crashes right before or during a fight, your champ loses half their health.
