This app is very glitchy & buggy @times. Biggest prblm is that it absolutely NEVER initiates or lets me log in over WiFi w/mobile data off. I just get a completely black screen when trying to open app or else I get a static, non-responsive login screen after many tries. It took me so long & much frustration of app never working to figure this out since every other app I have works over WiFi. Why can't my main phone app function over WiFi? Turning mobile data on & off is not easy & a pain. UGH!
