I can upload video to a shared photostream. I can see video in my and others photostreams. But I cannot save any video from shared photostream to my Ipad. It is declared officially that it is possible. But after I tap SELECT and tap a video in shared photostream, the DOWNLOAD sign in the left top corner does not become blue. It stays grey and does not offer any options if I tap it. If I do the same actions with any photo (not video) it works well. But with video it refuses to activate this download sign in the left top corner of the screen.
