The app won’t let you schedule two appointments with the same doctor. Once there’s an update available, the app won’t even open again so you can’t check your appointments, reschedule them or schedule a new one. The app should always be available even if a new version was developed. Even if I go to the App Store I can’t click update until the next day. I don’t want to delete the app as I may lose the data and I need to be able to consult my medical history. Very disappointing. App is also very slow.
