Why doesn't the autoplay setting work for Microsoft Stream video via Google Chrome?

The autoplay setting might not work for Microsoft Stream video via Google Chrome for the following reasons:

• Google Chrome blocks autoplay for non-muted content and creates a media engagement index (MEI) for every website based on user engagement. Google Chrome will allow videos to autoplay when the MEI score for a website is above a certain value.
  For more information about Google Chrome autoplay policy, see this Google article.

• In the Learn365 mobile app, by default, we use WebView with emulation of the Google Chrome browser. That emulator uses the same auto-play policy as the Google Chrome Desktop version.
  To resolve the issue with autoplay, change the default browser on your mobile device.
