I have self-hosted video file set as the background on this page: http://swanson-apts.com/
The file is only 4MB (http://swanson-apts.com/wp-content/uploads/2018/06/Swanson-OCLB.mp4)
The video works great on my MacBook Pro, however, my client is reporting that they only see the poster image.
On a Microsoft Surface Pro, running Windows 10, using both Chrome and IE, they cannot see the video.
On a Dell Latitude, running Windows 10, it works in IE but not in Chrome.
I’m guessing the theme reads the Surface Pro as a tablet and not a desktop and that’s why it doesn’t play. But why the difference between browsers on the Dell laptop?
