It's nice to see you all around the Community! 
To fix the issue with the synchronization I recommend to restart the tracker by following this steps:
1. Plug your charging cable into the USB port on your computer or any UL-certified USB wall charger and the other end into the port on the back of your Fitbit Charge or Fitbit Charge HR. Your tracker will begin charging.
2. Press and hold the button for 10 to 12 seconds until you see the Fitbit icon and a version number (e.g. "V30").
3. Let go of the button and unplug your tracker from the charging cable.
If this does not fix the issue, you can also try the steps provided by my friend @HelenaFitbit to fix this issue using different platforms.
Hope this helps and let me know if you need more help! It's great to have you in the Community!

Howdy @Nelldog and @Mimimusician, hope you are doing great and enjoying some healthy activities.
@Nelldog My recommendation is to follow the instructions I posted here for a general troubleshooting of the syncing problem. If this does not work, you can also check the requirements and specific troubleshooting depending on the OS of your phone. If you're using Android follow these steps, however if you have an iOS device try these ones.
@Mimimusician I'm glad to know that you were able to resolve the issue by yourself. If you have time please check our Discussions board where you will find other members sharing their experiences and tips for an active lifestyle.
See you around!
