Update got stuck at "Searching For WIFI Connection"
Realized that the WIFI connection within the Fitbit app needed to be updated since getting a new router recently. Problem solved. Hope this helps someone having the same problem.

There are no details on "bug fixes and improvements"
Best AnswerI have reset my wifi connections and verified connectivity, and the Sense still will not go through the firmware update. Keeps getting stuck and giving me a big red X. I turned the blutooth off and on, rebooted the phone. I finally gave up on it this morning and will wait to see if anyone has suggestions.
