Hi @Markbetty. Here is a solution that @Dawn126 mentioned in an earlier post. Please let us know if it works for you.
Here is what fixed mine. Several others followed my post on this and have had success as well. Let me know if it resolves the problem.
1. Go into settings on your iPhone and select Bluetooth
2. Look on the list of devices and see if the Charge HR (or the device that you have) is listed. If it is select the device and choose “forget this device”.
3. Turn Bluetooth off on your phone
4. Have your FitBit in hand. Open the FitBit app on your iPhone and as it syncs it should tell you that there is an update. You have to select update now and this should end up downloading the new software as well as sync with your Charge HR. This may take a little while.
*Note*
If the update doesn’t download the first time, definitely try it again as it may be stuck from the previous time.
