Hey there @Regret1 and @WendyB! A warm welcome to our new friend, I'm happy to see you here in the Forums @Regret1! Those threads have amazing tips for you to know. You can try to restart your Surge and phone too. Sometimes it is just the Bluetooth that is getting stuck while syncing, so force quite the Fitbit App and reboot Bluetooth too. 
Force Sync is done by going to Fitbit App > Tap on Account (upper right corner) > Surge > Sync Now.
