updated iPhone os can't find my Blaze

[Goldie61]

I updated my iPhone 7 to iOS 11.1.2 this morning and now I can't sync to my Blaze.

I turned bluetooth off/on, shut off the phone, deleted the device, reset the Blaze (left and lower right button on the Blaze)  Shut off all the apps. Nothing.

Now when I try to match my phone and Blaze - my phone doesn't find the Blaze.

I too have the same problem going from a charge2  to the blaze on iOS 11.1.2.

Remove omg the tracker will not fix this and will only add problems

If you have restarted the tracker and the phone and removed the tracker from the phones Bluetooth. 

Made sure the Fitbit app is updated. 

I would check the help docs out

I had a charge2 which I used for the past year until the band broke and it lost sync.  Upgraded to the Blaze.

The only thing I found to work is to:

1>  create a new email account or use a separate one not yet linked to fitbit.

2>  from the setup menu on the fitbit app on the iPhone7 select "join fitbit".

3> create a new login for the blaze using the new email account.   unfortunately this separate account does not merge any old data from any previously synched fitbit, i.e. charge2.   BIG PITA.

4>  all past settings need to be re-entered.

The take away: There is apparently no way to have the fitbit app running without a tracker and then have it recognize a new tracker on the iPhone7 running iOS 11.1.2.

Deleting my charge2 from the previously installed yet up to date app did not free it up to recognize the new blaze.   I even put the charge2  in the refrigerator (rfi shielding) to prevent it from trying to sync.   You need to start from scratch with "join fitbit".   BIG PITA.
