As iPhone 15s were released and as older iPhones began to upgrade to IOS 17 we ran into a problem that I have not been able to solve. We are unable to connect any devices, running IOS 17, to our Hidden Corporate WIFI LAN that is used for mobile printing. If the SSID is made visible these devices connect just fine; once hidden devices lose their connection immediately and can't locate the network. Apple Support, to this point, is refusing to acknowledge that IOS 17 could be causing this problem. The best guess, from Apple Support, is the possibility that the cloning of a new iPhone 15, from a previous iPhone might have corrupted something that can only be solved with a factory reset. This does not provide an explanation for devices that had no problem with IOS 16 but do with IOS 17. Has anyone else encountered this?
