Apple Issue with connection

Hello Everybody, I just noticed that the connection with AI Companion is bugged using iOS apple devices. I tried to use another apple device (Iphone 14 Plus) and it work correctly. Could someone please explain me why in some devices (older ones) apps work and in other devices(newer ones) they don't work.
Could someone help me, please?
Thanks in advance.

:question:

Which ones work/don't?

If you are running on iOS 12 and later, WebRTC is the default connection method and in the worst case should find a route between your devices and MIT. If you're using a device running an iOS version older than 12, then it will default to Legacy connection mode, which requires that the computer be able to reach the companion app on port 8001. If the network the devices are on doesn't allow this the the connection will fail.
