A few note past functionality but current state is broken; some mention no longer being supported. Overall, the app is viewed as unusable in its current state.

Every time I try to create an account the app says “couldn’t create an account, please try again later” it is frustrating and a waste of time.

I tried so many time to create an account and everytime it says “could not create an account, try again” I uninstalled it and reinstalled the app still the same!
