Fix bug where app signs out and pretends username/password are incorrect when you try to sign in again
Sometimes and randomly, the BabyTime app sugbs itself out (which happens only when returning to the app when it has been running [idly] in the background). When login details are entered again (correctly), the all says username/password are incorrect. This stays like that however many login attempts are do e and however much time is left between login attempts. The only way to log in again is to close the app completely (double tap home button and swipe BabyTime app off the screen), and relaunch. The app is then logged in already, no need to re-enter details. (I'm on iPhone 6 running iOS 10.3.3)
