Fitbit charge 2 won't sync with my phone anymore.

I had an iPhone 6s. Everytime when I tried to either activate the notification and all day sync, the app will said the tracker and my iPhone is not paired. But I my bluetooth settings said otherwise.

I have tried restarting the tracker and rebooting my phone, as well as re-download the app, but the problem presisted.

 Normally the message on the iPhone is "your tracker needs to be paired", with a button to press that takes you to the screen to approve. 

My thought would be to go into the phones Bluetooth and tell it to forget the tracker, but then I'm on Android.

I got exactly the same issue on my iphone6: no more bluetooth connection, all day sinc and notifications. According to my phone all is well and the devices are paired. I guess the latest update messed things up? Had new sleep stages for a couple of days that dissapeared as well. And Fitbit doesn't auto recognise outdoor bike anymor either. A bit messy, no?

I had the same issues too, the sleep stages stopped working. However, after rebooting my phone, reinstalling the app, and re-setting up the tracker, the bluetooth sync now works okay manually. But I am still unable to set up notifications and all day sync.
