Charge 3 GPS map doesn't show everyday

[2021Redge]

Same park, same route, same phone.

I have restarted my fitbit...

Fitibit Charge 3 v20001.88.11, iphone up to date.

I start my run from the fitbit. Used to always have a map, show the map.

Now the map display is intermittent?

Any input is appreciated.

Welcome to the Fitbit Community, @2021Redge.

Thanks for the details shared in your post and for already trying to resolve the issue. I recommend doing the following:

1. Force quit, and reopen the Fitbit app to refresh the connection with your device.
2. On your phone, go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Restart your phone.

4. Restart your tracker: How do I restart my Fitbit device?
