Same issue here, only way I could get it to pair was by using an old iPad running iOS12.
New sonoff mini device, I tried to pair with an iPhone running iOS 13.2 and I only could pair with a older android tablet.
@Robert Band I've all the most recent versions at the current date (iOS and eWelink app). I didn't enable the location services but now I don't need to pair the device because I used an Android device to pair. Maybe next time I can try your suggestion
I did try the location service with no joy before pairing with an older IOS device.
So i dont think unless i done it wrong the location service fix is a fix?
Same here, enabling location services made no difference.
Very lucky then I guess. I've tried 3 different Sonoff devices.
I have a few more devices on the way so will give it another go.
I've had this happen to me twice now - each time the solution was to disable/re-enable location services, then reboot my phone, then immediately perform the pairing. Rebooting seemed to be key.
