Synching with iPhone XR

[Trixie72]

Since Wednesday last week my Fitbit has lost connection to my iPhone and no longer updates my progress throughout the day and also doesn’t sync when I try to do it manually

Hi @Trixie72 - not syncing can be one of the problems with the new V4 Fitbit App.

Toggling Bluetooth off/on, and sync, if not restart phone and watch and sync.

If stii unsuccessful try removing the Sense 2 Bluetooth entries from the phone, Logout of the Fitbit App and swipe off the active window and then restart the phone.

Make sure there are no other devices running the Fitbit App switched on or other watches.

Restart the watch.

Login and wait for any pair, link or Fixit prompts to set up new Bluetooth entries, to help the process if need be, go to the Device page in the Fitbit App and Add more devices, select your watch and replace.
