Have unpaired devices from previous phone. New phone will not find any devices under Bluetooth or Apple Watch.
ok, I got mine working. My iPhone 15 is now updated to iOS 17.5.1. To get my Series 5 Apple watch to pair, I had to do a factory reset on my watch, remove my plan, etc and then set it back up.
I didn't have to do any of that with my Ultra 2 watch.
Now that Apple has fixed their Bluetooth OS defect in this iOS version, I can pair with any of my Bluetooth devices, however, that almost always requires me to manually put them into Bluetooth acquisition mode, i.e. conventionally indicated by an alternating blinking red-blue light.
I'm not going to thank Apple for fixing a defect their testing should have caught so they didn't inconvenience their customers and waste countless hours and frustration trying to figure out why the earlier iOS versions wouldn't pair correctly.
One thing is for sure, though. I'm not going to trust another iOS major (17.n.n) or minor (17.5.n) version release until it's at least at the 3rd or 4th iteration, e.g. 17.5.3|4.
As a result of the trust I have lost with Apple, I have turned off auto-updates and will now manage them manually.
Who said I was referring to people in this forum? I'm not. My comments are directed towards Apple. That seemed obvious to me but I can see where you might misunderstand.
