Last night after a work out the Microsoft Health App wouldn’t find my band. There was an issue with bluetooth pairing so I tried disconnecting, reconnecting, and re-pairing, but the app still could not find it.
Some one else had the same problem and was able to fix it by reconnecting until two bluetooth devices connected. I tried to follow his advice, but mistakenly shrugged off a warning and I was left with a Band that would no longer sync until a factory reset completed.
I found out too late, before I unregistered, that you can also pair the band to the desktop on Windows [discontinued] or the Mac App Store. I bet I would have been able to sync up and upload the workouts that I lost.
For those few who have a band Microsoft recently pushed out its first update for the band itself, only available when using one of the mobile app.
