The app kicks me out while I'm working. Refresh or “try again” doesn't work. I need to close the app and sign in again to continue working.

Furthermore, I constantly get the error message “Sync fail” while working. Retry usually works, but currently I don't trust NovelCrafter anymore. I've only recently started using the app. Unfortunately, my previous impression is negative, I'm afraid of a data loss/crash.
