Fitbit Charge 2 won't pair with new iPhone 8
I bought my wife a new iPhone 8 and gave her my Fitbit Charge 2. I cannot get the phone to find and connect to the device. I've tried all the troubleshooting advice I could find online including on the fitbit site, no joy. I am able to pair the device with my iPhone 7 and a couple of other iPhones. The problem follows the iPhone 8. Anyone else having this issue?
iMac (27-inch, Late 2013), OS X Yosemite (10.10.5)
