I like my sense but...

The reliability of the watch and the phone app (Android) is poor. Force quitting the app and restarting the watch have become part of my daily ritual (perhaps it deserves a special badge 😀). When I do this features start working again. It's very frustrating and I'm looking forward to one hell of a set of updates!

I like the idea of a badge!

This might help, depends on your phone.

On the phone check battery optimizations

[the options may be different in your version]

• First go to Settings > Apps & Notification > Special app access
• Click on Battery optimization
• Now press the drop down menu [...] and select “All Apps”
• Click on Bluetooth and then select “Don’t optimize”
• Same with Fitbit
• Next go to Settings > Apps  > Fitbit > Storage
• Clear cache [not data]
• Force stop the Fitbit app

And for good measure:

The shutdown the watch [hopefully for the last time!], restart the phone and place the watch on the charger to start it.
