I added a self hosted video as background video. And on touch devices this will be replaced by an image. This works fine on Android devices but on an Iphone the video is still in the background and I think this blocks the touches. So, it’s not possible to press any button in the homepage when running on Iphone, because the touch gets blocked by the video. When I touch exactly in the middle of the screen, the video starts.
So how can I fix this bug?
