"Notification System not running" message

[TonySeet]

I'm getting this "Notification System not running.  Reset your mobile phone ...." daily.  I'm using Xiaomi android phone and Fitbit sense 2 watch.  This started happening shortly after the recent "time zone error" problem that I got on the Fitbit app.  I had reset the mobile phone several times, make sure that no restriction of battery consumption by Fitbit, re-installing the Fitbit app, re-pairing the sense 2 to the app, and many other checks/resettings with no permanent solution. 

Please assist 

Thank you.

I like to share that my attempts to rectify my problem of the Notification System not running have finally produced a good result. 

I discovered that I missed out a step in the setup on the app : ie enabling  "Background autostart" for the Fitbit app. 

After enabling "Background autostart", the Notification System has been running since then (more than half a day ago) and it's still running.
