I've been using the web version to avoid issues but for the last 2 weeks it has developed issues on Macs. If you use any background setting for your privacy it results in the video turning black if in meetings you change the focus to external chat, calendar or turn off/on on camera. This was also present on windows a week ago and been fixed but the Mac is still left with the issue. This impacts intel and M1 macs. I've only got 12.3 and 12.4 OS and impacts those. Present on safari, edge, chrome and firefox.
