I've tried over several month and it's always the same. I've successfully shared dozens of files and videos from my iMac pro computer so I understand the process. However, anytime I'm hosting a meeting on the same computer and want to share my USB connected iPhone screen to the meeting, it never shows up so I can't.
I'm using macOS Monterey 12.3.1 and Zoom Version: 5.10.4 (6592) and my Finder shows the wired connection to the iPhone so my computer knows the phone is connected. When I click on Share Screen, there is no option displayed for my iPhone. Attached screenshots. One of the photos shows what I think I should see (from the Zoom help page) since it is a wired connection but my options never show that. The other two photos show my options to share on the Basic and Advanced tabs. The Files tab is similar so I didn't put the screen shot here.
I am having a similar issue and wondering if you ever found a solution. I am trying to share my ipad in my Zoom meeting however the option to share iPad via cable does not show up as an option. I d have the option to share via Airplay however our network does not allow Airplay. Really would like to get this functionality to work.
