Sense isn't receiving notifications

[Lanybum]

Recently purchased a Sense and I'm having real issues with notifications. 90% of the time they don't work and I get the following message in settings "notification service not running. A phone restart is required to re-enable notifications on your tracker". 

A restart doesn't help.

Any ideas. It's driving me insane. 

Thanks.

try

In Android phone Settings *

Apps

Fitbit

Storage - clear cache [not data]

Force Fitbit shutdown

[though it doesn't seem to fully]

Log back in to the Fitbit app

*Quick Shortcut: Press and hold the Fitbit launch icon, then App info [on some phones]

For IOS uninstall/reinstall the Fitbit App & remember to do the notifications settings you need again

Thanks @Guy_ .  Thanks for response. Have just tried that but didn't work unfortunately. I have heard form Fitbit though and apparently this is a known issue with Hauwei. Fitbit have said they are aware of it  are working on but no indication of timeline for a fix.

Thanks for the update, did you restart both watch and phone after the change to make sure it takes effect fully.

Though as you have a Hauwei it may still require a fix from Fitbit.

I did indeed. Still no luck. Hopefully they get it fixed soon.

Thank you for the confirmation. Sorry you have to wait.
