  • Known issues for Application Sharing beta:

    • Sometimes, when several applications are open on Windows 10, not all open application windows appear in the Share Application selection menu. We recommend closing unnecessary windows and trying again, or using the Share Screen option instead.

    • Sometimes, your edits to a document aren't visible during application sharing. For others to see your updates, you may need to stop and reshare the application. You can avoid this problem by using Share Screen, where users can see your edits in real time.

    • With macOS Catalina (10.15), Apple introduced new security and privacy features for Mac devices. In order to share your screen in the Meetings web app, ensure that your browser has the Screen Recording permission enabled.

      In your device System Preferences, give your web browser privacy permissions, and restart your device for the changes to take effect:

      If you don't grant permissions, you may see the following prompt when trying to share your screen:

  • Presenters can’t pass keyboard and mouse control to attendees who join using the Meetings web app.

  • You can’t request control when a user is sharing from the Meetings web app.

  • Attendees who join from Internet Explorer browsers can’t view other participants' videos, and can’t turn on their own video. To view other participants' video and turn on your own video at the same time, we recommend that you:

    • Switch to the Meetings desktop app.

  • The web app doesn't support Virtual backgrounds.

  • Grid View in the web app supports up to six videos, with a maximum resolution of 180p.

  • Sometimes, in Grid View, when several people are talking back to back, there’s delay in the active speaker video response. The delay can cause the video to look duplicated for a brief moment.

  • You can't switch seamlessly to the desktop app if you're using the web app in a private or incognito browser window. You're prompted to install the desktop app, even if you already have it installed. To avoid this issue, launch the desktop app manually.

  • Meeting Options can not be managed from within the web app.

  • The web app does not support entry and exit tones that are configured in an event.

  • When switching from the web app to the desktop app in an event, you must manually reconnect to audio in the desktop app.

  • Audio broadcast is currently only available in Chrome, Firefox, and Safari.

    • There is a rare case where, if the host unexpectedly gets dropped from the Training session, it may look like the host role was automatically assigned to a user in the web app, though they, in fact, do not have host privileges. In this case, the host role may be reclaimed by a participant in the desktop app.

  • Web app users can't view whiteboards or shared files in breakout Sessions.

  • You can't create breakout sessions from the web app. We recommend using Meetings instead.
