Hello Zoom Developers, here are the updates for the **Web Video SDK version 1.2.3 release** 🙂

## Added

- Support for users to join session before host

## Fixed

- Issue with Command Channel having unexpected failover behavior when ending a session
- Audio and video not reconnecting properly on failover
- Error code not being sent correctly when no server responds to connection requests

## Known issue

On Chromium, video stops playing and goes black when resolution changes to or from 720p. This is caused by a [bug in Chromium](https://bugs.chromium.org/p/chromium/issues/detail?id=1301897), which is due to be fixed in Chrome 101, [scheduled for release at the end of April](https://chromiumdash.appspot.com/schedule).

To work around this, you may reduce resolution below 720p. Alternatively, if you’d like to continue using 720p, you can recommend that your users toggle their video resolution when they experience this issue; for example, by adding a toggle button or messaging to the user.

@tommy The chromium bug you mention is also affecting the Web meeting SDK i guess ?
