Welcome to the Fitbit community, @LynC52!

Sad to hear that you're having an issue with your Charge 6. To hopefully get things fixed, please make sure your device is not set to Quiet mode by going to Settings and then checking these options:

Also please have a closer look here:

How do I get notifications from my phone on my Fitbit device? 

If none of those will work for you, I'd suggest restarting your Charge 6. Before doing so you should make sure you've synced your device to not lose any data tracked so far. Also you should verify that the charging contacts on your device are clean and the charging pins on it's charging adapter are clean as well and can move flawlessly. In doubt please have a look here:

Next please closely follow these instructions as timing is crucial for this procedure:

1.) Connect your Charge 6 to the charging cable which has to be connected to a reliable power source.
2.) Press the button located on the flat end of the charging cable 3 times within 8 seconds(!), holding each press for about 1 second(!).
3.) Wait around 10 seconds until the Fitbit logo appears on your device's display.

I'd like to point out that it sometimes requires more than one attempt to restart Charge 6. So, before throwing the towel, please give it another try

I'll keep my fingers crossed.

I’m having the same issue. It started when Google took over. ☹️
