I recently decided to start using my Fitbit Charge 3 to receive notifications from my iPhone again. When activated, the Charge 3 can receive SMS, Calendar, and call notifications from your iPhone.
I had the settings in the Fitbit app on my iPhone set to “All Day Sync” and notifications turned on but I still was not receiving notifications on my Fitbit.
I searched online and followed all of the guides that would supposedly fix this, but none of them worked for me.
I finally realized the Fitbit itself had the Notifications setting set to off. All I needed to do was hold down the button when on the Notifications screen, pictured below:
So if you have exhausted other solutions, make sure the Fitbit’s setting is set to receive notifications on the device itself.
