Hi, @2rivers2! I would suggest trying to restart your tracker a few times.

There is a button on your charging cable to restart your tracker. Plug it in and press the button. Try doing it a few times.

Hello @2rivers2, thanks for joining the Fitbit Community, it's great to have you on board. It's nice to see you too @MakMak, thanks for all your help. 

@2rivers2, as @MakMak mentioned, it's a good idea to restart your Alta, sometimes this is the only step needed in order for a tracker to start syncing again. You can find instructions in how to restart it in this post. However, if after restarting your tracker it's still not syncing, I would like to suggest you the following:

• Make sure the latest version of the Fitbit app is installed on your phone.
• The software on your mobile device is up to date. To check, tap Settings > General > Software Update.
• Make sure there are no other Bluetooth devices around as they might interfere with the syncing process
• Check that your Fitbit device's battery isn't critically low.

If your device still won't sync, try these steps:

1. Force quit the Fitbit app. 
2. Go to Settings > Bluetooth and turn Bluetooth off and back on.
3. Open the Fitbit app.
4. If your Fitbit device didn't sync, restart your phone again.
5. Open the Fitbit app.
6. If your Fitbit device didn't sync, restart it one more time.
7. If your Fitbit device won't sync after the restart, log in to your Fitbit account on a different phone, tablet, or computer and try to sync.
8. If your Fitbit device still doesn’t sync, remove all other Fitbit devices from your account and from the list of connected Bluetooth devices on your mobile device and try to sync.

I hope this can be helpful, give it a try and keep me posted in case you need anything else.
