Hi @Catherinemac! Welcome to the Fitbit Community!
Let me help you out, I recommend you following these instructions:
- Close the Fitbit app and open it again. A sync should occur whenever the app is opened.
- Turn it back on, and then open the Fitbit app.
- Reboot your mobile device and then open the Fitbit app again.
- Restart your tracker. For more information, see How do I restart my tracker?
- Uninstall and reinstall the Fitbit app.
- If your tracker didn't sync, try syncing with your computer.
- Try turning on all-day sync so that your tracker will periodically try to sync with the Fitbit app. Note that some customers find that this feature causes the battery on their mobile device or their tracker to drain more quickly than normal.
Hope it helps :D. Let me know how it goes!
