IOS app can’t find Fitbit after Firmware update on Charge 2

[KarenHealth]

Last night I was prompted to update my Charge 2 Firmware. I did. But now this morning my latest Fitbit iOS app can no longer “find” my device. It has left me unable to sync my device to my app. Any fixes? (Charge 2 forum has lots of users reporting lots of problems after this rolling Firmware update).

My zip is doing the same thing.  Both my iPad and iPhone app were unable to "find my device" after the app updated.  I forced closed them. turned bluetooth on and off, etc...  Very frustrating.

Same issue with my Flex. Worked fine this morning until I updated the app. As others have done, I’ve run all the recommended fixes with no results.

Same issue with my One. Stopped syncing with IOS devices right after updating app.

Yeah and now I’m not getting any notifications ... kind of wishing I’d just
got apple watch now!
