Some instability bugs and crashes
Im using iOS 9.2.1 on an iPhone 6S+.
This is a pretty decent chat application. Create rooms, add friends, give permissions, add custom icons to chat rooms, so on and so forth.
Occasionally all chat histories disappear upon reopening or swapping into the app despite not explicitly clearing them.
The app crashes somewhat randomly, although it seems to be most often immediately after swapping into the application from a different one. This does not happen as I swap between or to other applications I have active in the background.
