most of the epub eBooks purchased from Google Play, Kobo, or other ebooks stores are protected by Adobe DRM. In general, those DRM epub doesn’t support by iPad ibook, because of the DRM limitation.
Here I’m very pleased to tell you that I’ve found the reason and the solution. And this is also the reason why I write this article. The more people know the news, the happier I would feel.
