I've had my share of issues opening the app.
I had to quit on my old phone, a Galaxy 4 because after a certain update it crashed during loading every time I opened it. I've got a used 7 Edge now.

I've still had times when it would be unable to process my login information or just freeze with a 'sign out' button popping up during loading.

I also had trouble getting into the raid I participated in yesterday afternoon. It kept freezing and telling me there was a network error but shutting off wifi seemed to solve that problem.

As for ghosts, Gastly has been a relatively common encounter in my area but they're hard as hell to get into a Pokeball so I've sworn them off and intend to just do the buddy system with my Haunter.
