The embedded poll feature is not yet available in Stream (on SharePoint). However, it is important to note that you will not lose access to any existing polls after Stream Classic is retired: polls attached to Stream Classic videos will continue to be available via the Microsoft 365 Forms app as they are stored separately. We will update the community if/when this feature becomes available for Stream (on SharePoint). Alternative solutions at this time could include: 

• Pasting a link to the poll in the video’s description on Stream Classic. 
• Adding a video to a Forms poll using these instructions. 
• Creating a SharePoint page to show a video and a poll side-by-side. Please reach out to the University’s SharePoint team via uoft.me/sharepoint for more information.
