- Video resolution is larger than 1920 × 1088 ( https://www.caniuse.com/?search=video > Known Issues )
- The videos contain no audio track ( https://wordpress.org/support/topic/mp4-h264-video-doesnt-al... )
Anyone else have ideas?
Other than that, I'm not sure. I've added direct media links under each video - hopefully that works until I can try some fixes.
