I have troubles with Firefox account verification on Android device (Huawei Nova, Android 7.0). Firefox is up-to-date. In account section of settings, I see a warning "Your account is not verified. Tap here to send verification email". I have followed the instructions, received the email and verified the account. However, the warning is still there and sync is not working. Tapping the warning now leads to account settings, "sync now" does nothing. I have tried force closing the app and clearing the cache, to no effect. Account works in another device (PC, Ubuntu). I would appreciate any help.
