PowerPoint application on Mac does not play the embedded YouTube video.

Hi!

When inserting a video with a YouTube link into a PowerPoint presentation, the video does not play; it remains as a static image.

• The Powerpoint file was created in the Mac.
• This happens with all files.
• The files are on the Mac desktop.
• The same PowerPoint file plays the video without problems from Windows.
• The same file plays the video if I open it from OneDrive online on the Mac using Safari.
• PowerPoint and Mac are updated.
• The behavior is the same on two different Macs.
• Until recently, YouTube video playback in PowerPoint presentations worked without problems on these Macs.

Thank you very much in advance for your help!

Kind regards

Diane
