  • 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 and prepare and run Slido from there.

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

  • Participants can use Slido on the Meetings, Webex Webinars and Webex Suite Meeting Platform desktop, mobile and web apps.

    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.
