I have created a simple animation in Adobe animate , saved it as an OAM file. Placed it in InDesign and created a fixed epub.
The problem is that it works just fine in Ibook on my desktop computer, but the animation does not show when I test it on my ipad air.
Does anyone have an idea of why?
It's a known issue. I don't think there's currently a workaround. It appears to be an issue in the iOS version of iBooks.
There are issues on iBooks on iPad because of which oam files are not visible on it. Following discussion have more information regarding same.
