I stopped using Teams on my iPad months ago because it was impossible to use the camera while looking up e-mails, so I’m quite amazed this was possible with Zoom (apparently my kids have been using it in school and thought it was a standard feature, so it never came up).
I completely get the need for entitlements (and curtailing their use when they’re privacy sensitive), but I have to wonder why this isn’t available to every major conferencing app (including WebEx, which Apple itself uses internally and that I had to resort to a couple of times recently).
