Powerpoint 365: Video across multiple slides

This has been a troublesome tool in PowerPoint for Mac going back many years.

We never use PowerPoint now to do this, instead Keynote works perfectly

1. place the video file on the slide where it is to start playing from
2. Add the video to each consecutive slide you want the video to play across.
3. On each slide, click the file to select it, click the Format button, click Video, then turn on “Play video across slides”. 
4. Turn off “Play video across slides” for the last slide you want to play the file across.

These are Apple forums. For a better chance of getting the answer you need, consider asking this in the Microsoft's Support Communities. Start Here: Microsoft 365 and Office - Microsoft Community

Contact Microsoft Support:

Also, ask Microsoft what they have to say on this.

Based on Personal Experience: Just be careful, as they will ask you for access to your computer. So, do not share the screen with them. Unlike Apple, Microsoft has full accessibility to your computer, tapping and opening what need be. So, just stick to the chat, when it comes to remote support with Microsoft.
