@SunsetRunner Welcome to the Community Forums.
Thanks for the details shared in your post and for the troubleshooting tried prior posting. Note that connected GPS feature on your Fitbit Charge 3 works with the GPS sensors in your nearby phone. To get GPS data, including pace and route for your workout, you must select a GPS exercise from the Exercise app on your device and bring a GPS-enabled phone with you. We recommend turning off Wi-Fi on your phone when using connected GPS to improve the experience.
When you choose a GPS exercise, your device vibrates when your phone finds a GPS signal. If your phone doesn't find a signal immediately, keep in mind that environmental factors including tall buildings, dense forest, steep hills, and even thick cloud cover can interfere with your phone’s ability to connect to GPS satellites. For more information see, How do I use GPS on my Fitbit device? For best results, wait for your phone to find the signal before you start your workout. However, if you don't want to wait you can start your workout and GPS tracking begins when your phone finds a signal.
After taking in consideration this information, try using GPS again by following the instructions in How do I track my workouts with my Fitbit device?
If you're still having difficulty, I suggest trying these troubleshooting steps:
Force quit, and reopen the Fitbit app to refresh the connection with your device. For instructions, see the Apple help article
On your phone, go to Settings, Bluetooth and turn Bluetooth off and back on.
Restart your phone.
Hope this helps.
