Fitbit Charge 3 won't stay connected to my new iPhone 12

[CocoD]

Prior to getting my new iPhone 12 the only issue I had with the Charge 3 was that I couldn't see the display in daylight which I gather is a common problem.  Now with my new phone it won't stay connected.  It says "Lost Bluetooth Pairing  Go to Bluetooth settings, forget Charge 3 if it is paired and then go back to app and wait for pairing request".  I have done this multiple times and it doesn't help.

Hello @CocoD. It's nice to see you around! 

Thank you for the detailed information and for the steps you've followed prior to posting. Regarding the brightness screen inconvenience, I'd recommend taking a look at this thread that contains some tips and suggestions. 

For the Bluetooth pairing inconvenience, I'd recommend making sure that there aren't too many devices paired to your phone's Bluetooth; otherwise, please remove other devices paired to your phone and test the behavior of your Charge 3. In addition, I'd recommend performing a long restart to your Charge 3 by following the instructions below: 

1. Connect the device to the charging cable. 
2. While the device is plugged into the charging cable, press and hold the button down for 15 seconds. 
3. The device turns on and shows a battery icon. Two vibrations occur: first a short vibration, then a medium vibration. 
4. The device turns off.
5. The device turns on and shows a progress bar and short vibrations occur. The progress bar completes. Note: A total of 7 short vibrations occur. 
6. Remove the device from the charging cable. The device shuts down.
7. Important: Plug the device into the charging cable again.

Hope this helps.
