Incident Report

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.
