I have had that problem for about a year. Forerunner935 won't Bluetooth pair with iPhone. Have followed all the recommendations from Garmin support. Factory cleared and reloaded all software on both iPhone (without using a backup, clean install) as well as 935. The iPhone can connect with other bluetooth devices ok. Also the 935 watch will pair with a Windows laptop. But the iPhone and 935 never see each other over bluetooth.
To make matters worse now the 935 watch will not successfully complete a WiFi sync since last upate a few weeks ago.
