Hello! I hope you're well.
I have an intro video that autoplays on page 1 of my e-book (EPUB)
It works great on a Mac, but does not play on my iPad. It just shows a black screen. I'm trying to watch it in Apple Books app.
The video file is H.264 .MP4 and I just can't get it to work.
Does anyone here know a fix for iPad??
I have to upload the EPUB to Apple in 2 days, so I'm starting to panic a bit...
