App crashes

When I have the app open and either trying to enter a gym or select a Pokémon to catch it or even going to a pokestop, the app will crash and kick me out of the game. The other day, I was in the middle of a raid for a Charizard and I couldnt switch onto my next Pokémon (or I couldnt see it) and I was kicked out. Took me awhile to re-join, but I couldnt do anything but look at the Charizard, this wasting the one-a-day free raid pass.
