PUSH don`t work on my boox max 2 pro after updating 2.2.2

My account works rightly on web, but don`t work on device.

And the login process was also difficult. Strangely, it said that the authentication number received by the mobile phone was not valid. But the login was successful when it tried to log in after exceeding the input time.

I’m still logged in in Settings, but no files appear in the Transfer app.

How could do I do?
