What should I do if OTP service on 2FA is not working?

Updated 

We would recommend you to:

  • Check if the time zone on your device is correct
  • Sync Google Authenticator by tapping on the Menu button (three dots)
  • Go to [Settings] and then click [Time Corrections for Codes]
  • Select [Sync now]

The OTP service on 2FA should work fine now.
