I had the 5s and have recently got the 6 but the band - which ran perfectly on the 5s - will not sync on the 6 no matter what I try. I've tried forgetting device on other phone, bluetooth off everything but the items I am trying to do, syncing via app and syncing via the phone's "find my devices" but nothing is working. The band reckons it is compatible in the instructions and on various sites but everything I am trying is failing :(
Hoping someone here might know something I don't.
