I bought my fitbit versa from Bangkok International Airport on Friday. I have set it up and it was working for one day, after some updates the sync stopped for notification and the error message that reads is 'Notification Service not running. A phone restart is required to re-enable notifications on your tracker.'
I have restarted my phone and have tried to factory restart and reset and everything many times but this notification keeps coming. I get calls but no messages and no apps notifications.
