Fitbit not sincing

[JoA]

Charge 2 Fitbit won't sinc since the last update!!  Deleted app reinstated, still not sincing. Can't recognise device... Do I need to perhaps remove device and reinstall?

I wouldn't remove the device as this can cause further problems.

Instead I would try restarting your phone and then restarting your fitbit using this procedure:

1. Plug the charging cable into the USB port on your computer or any UL-certified USB wall charger.
2. Clip the other end of the charging cable to the port on the back of the tracker. The pins on the charging cable must lock securely with the port.
3. Make sure the button on your tracker is aligned with the button opening on the charging cable. You’ll know the connection is secure when the tracker vibrates and you see a battery icon on your tracker’s display. Your Charge 2 will begin charging.
4. Press and hold the button on your tracker for four seconds. When you see the Fitbit logo and the tracker vibrates, this means the tracker has restarted.
5. Unplug your tracker from the charging cable.

Give this a few tries as it doesn't always work. If it still won't sync after that then there are some more ideas to try in this help file: http://help.fitbit.com/articles/en_US/Help_article/1866

How do I put my Fitbit off & back on?

Sorry I don't understand the question.

Settings / About / Shutdown.

I had the same problems but nothing worked for me so I took mine back to the shop and replaced it with a Garmin. 

Good Luck
