    We've identified an issue in the recently released Chrome 143 that prevents sharing a browser tab in screen sharing from working in BigBlueButton. We have a fix in place and are rolling it out now. The fix should be available to all users within the next 24 - 48 hours. As a workaround, we recommend any user wanting to share a browser tab in Chrome 143 to share application or full screen instead.

    Updates rolled out over the weekend. Sharing of browser tab in Chrome 143 now works again. As an added bonus, Chrome on Mac OS X now supports sharing of system audio when sharing desktop!
