content: I used to love this app and used to be my go to app for cross compatibility among all 3 platforms of android iOS and windows But for the last month or two have been having trouble to sync my one note from my Android phone. It always shows up as error and requires me to sign in again and it wont let do it on WiFi. Even after switching to mobile data and logging in some notebooks dont Sync. I have to uninstall and install the app every time I have this issue for proper sync.
