iPhone 5S won't synch w Fitbit Flex
I bought a Fitbit Flex today and it synchs nicely with my MacBook Air but not with my iPhone 5S. The phone's bluetooth setting is On but it doesn't see any devices and just keeps searching. The Fitbit app however, thinks the bluetooth setting is Off. I have the latest version of iOS. I just updated it yesterday.
I've gone through all the trouble-shooting steps suggested by Fitbit: resetting the tracker, relaunching the app, setting up the Fitbit as a new device again. To no avail.
Any suggestions?
iPhone 5s, iOS 7.1
