Does this game crash on you?

My app crashes a lot when I am in the lobby, but usually I can restart and get back in. One time the battle ended just as I got back in, and I spent a raid pass and got nothing. But that was only one raid out of about 20.

When does it not crash on me?
I check a gym? 30% chance of crashing.
I've somehow managed to get out of the gym without the app crashing? GPS Signal Not Found or character just sits there, no longer following my walking.

Iphone 6 Plus and it constantly crashes, especially in Raids and battling gyms, but also when just walking around catching mons and spinning stops. It's borderline unplayable, but I just keep on restarting the app and keep on trucking. I think it's my phone though. My battery drains like crazy playing this game too.

It has crashed in almost every tier 3 or 4 raid I've been in, as the longer the battle goes, the better the chance it crashes. And as someone said, there's also a chance it crashes every time you visit a gym, which is annoying since the app takes longer to load (and needs to reload everytime you close the window--it used to run in the background).

I tried a magikarp raid the other day just to see if it would crash. Got stuck in endless loop and timed out. Magikarp took 8 SE from a 3400+ Ttar and still lived. What a waste of a pass! Fix this crap!
