Recently the app just extremely frequently fails to connect at all, seemingly when something happens such as switching from mobile data to WiFi, or vice versa. It'll simply just be stuck on "connecting", and I'll either have to try and clear the cache (which... Sometimes work, but not often), or be forced to restart my phone, which I now simply refuse to waste my time on. For a company so big, and for one of their flagship communication products, it baffles me how sucky they manage to make it.
