Welcome to the Fitbit Forums @Daph72! Have you tried these syncing troubleshoots. Make sure that there isn't another bluetooth device that may be creating interference during the process. Setting up your tracker as a new device may also help you to bring it back to sync as usual. Also, make sure that your mobile device is running the latest version of the Fitbit app for iOs.
Let me know how it goes.
