Limitations

  • Slido isn’t available to meeting hosts in Site Admin managed sites, unless the site and users are linked to Control Hub and they use the same method of Webex authentication as Control Hub-managed users.

  • Microsoft Edge WebView2 is required, if using Windows.

    Otherwise, Slido prompts you to install it on first use and WebView2 downloads from Microsoft. Download and install can take several minutes, which could impact your meeting experience.

  • Slido isn't supported in meetings from a space in the Webex App. Slido can be launched and managed from the Meetings desktop app or from full-featured meetings in Webex App. Hosts can also go to https://www.slido.com and prepare and run Slido from there.

  • Webex room devices and desk devices for hosts aren't supported.

    Slido on personal devices is only supported for participants in Meetings and Webex Suite Meeting Platform.

    To add a collaborator: Open Settings from Slido panel and add collaborators to help you manage Slido in Webex Meetings.

  • The color theme in Slido doesn't match the color theme in Meetings.

    Workaround: There’s an option for hosts and meeting participants who launched Slido to customize the colors for participants.
