Sat in on a Zoom meeting about Photography. Idiot unprepared presenter first held up his iPhone to the camera, asking if we could see it. No, it was hiding in his virtual background image. He said he'd taken a selfie & would show it by the magic of iCloud by logging-in to the meeting from his iPad & sharing the screen of that, his reasoning being that greater screen area would work better as a shared screen.
This chap was otherwise using a Windows 10 laptop with the Zoom client on it.
I knew for a fact that both the Windoze & Mac clients could use screenshare to show an iPad or iPhone's screen and was trying, politely to let him know of this method. Zoom does iOS screensharing in a seriously weird way from the iOS client software & I knew it was going to confuse the fuck out of him.
I gave up being polite. I announced to the other participants that there was a far better way to display what he wanted & if he wasn't prepared to listen or even acknowledge my efforts, then I was leaving the meeting.
He's normally much better prepared than this episode would suggest.
Fuckwit.
