Can’t log in with my Facebook account – Pianista Review

The latest update allows me to log in with Apple ID but then I frequently find out that I have problems logging in with Facebook. I have to register a backup account using my Apple ID so that I can still play. But that means I have to play from scratch...I really want my Facebook acc back. Every day, the first try of logging in with Facebook seems successful, but after all things done it will tell me the internet connection is unstable. And if I click on the “retry” button, I have to log in again, but this time (and every time afterward) I can no longer open the log in website on my Facebook app. I have to wait for another day but only to see this situation coming back again. Wondering if it is just me or others also have the same problem.
