On both my iPhone 6s Plus and my cellular iPad mini 4, after a reboot, both devices won't join my WiFi network until AFTER I enter in my passcode for the first time (as TouchID is not supposed to work the for the first unlock after a restart of the OS). Both devices are on Verizon. Edit: It also happens on my WiFi-only iPad Air 2, but not my sixth generation iPod touch, so maybe it's only on devices with TouchID and/or a passcode enabled? I know that this wasn't always how these devices behaved and it is happening on more than one of them, so I'm confident that I don't have defective hardware. Has anyone else experienced this and/or knows more about the issue? I'd imagine that this would be quite bad for anyone on a metered data connection.
