So... Perhaps foolishly, I recently endeavored to update my 2017 iPad 5 to iOS 11, in hopes that it might fix more problems than it causes; but sadly, it seems this is not the case —Ahem!
Anyway, since updating to iOS 11, iConfig can't seem to find the iConnectAudio4+, and the iPad will no longer accept a charge from either of the device ports. I rebooted everything several times, loaded apps in different orders, disconnected and reconnected the lightning cable at both ends several times, and employed all the usual troubleshooting measures to no avail.
That said, when I first plugged the iPad into the 4+, it did start charging; but after a few minutes it simply stopped, after which it would not reconnect despite my best efforts. And after an hour of fiddling about, iConfig did momentarily recognize the 4+ only to drop the connection in short order.
I'm running all the latest firmware, and iConfig on my Windows machine is recognizing the 4+ as per usual, so... Anyone?
