So here's my update and the fix that worked for me.
Mine broke along with everyone else's with the Aug 15th update. I've been able to fix the sync, temporarily, by rebooting my Versa and my phone. That will usually allow it sync at least for an hour or three.
On Thursday I finally got some free time to try to fix it.
1 - Make sure your fitbit is fully charged as this will take a bit and will most likely drain a considerable portion of the battery.
2 - Remove the fitbit from your app/profile
3 - Remove the app from your phone/tablet, etc
4 - Force your phone to forget the device in your list of bluetooth devices.
5 - Factory reset your fitbit device.
6 - Reinstall the app, login etc.
7 - Setup the fitbit as a new device.
In my case this it looked almost like it re-loaded the firmware onto my versa, version # was the same.
I did this on Thursday and as of Saturday night I have not had any syncing issues since doing all of this. My best guess is that the app update broke something within the firmware of the device or maybe even did some type of incremental update to the firmware that corrupted it slightly. Factory reset appears to essentially put the fitbit into a low-level mode that the app uses to do a full load of the most recent firmware.
