The day after my iPh13pro announced it updated to iOS 18.3.2, Screen Mirroring, which formerly worked fine via a private WiFi network even though I used another network to access the Web, now instantly quits when I switch back to the main ISP WiFi.
It's not that it doesn't work, just that it's useless if mirroring instantly dis-continues after I switch to the WiFi that connects me to the rest of the planet.
Extremely disconcerting since I spent ~$300 and spent hours and hours finding a display and wireless HDMI adapter that could both mirror an iPH1 in PORTRAIT mode and not waste screen space not two weeks ago. Now the entire setup appears useless.
