- If the step one does not help, then force restart your iPhone and try to force a sync between the Charge 4 and your iPhone.
- If the step two also fails, try to pair your Fitbit device i.e. the Charge 4 activity tracker with another phone. Now, try to do a sync between this phone and the Charge 4. This step should, actually, tell you if the issue is with your iPhone or with the Fitbit Charge 4 fitness tracker.
Sadly, you cannot do anything more beyond a point. If your iPhone and Charge 4 refuse to work together after all this troubleshooting, it is suggested that you contact the Fitbit customer support.
