i accidentally posted a bunch of pictures in the wrong-named album. Often, when I'm trying, I select the album I want the picture moved to. I click on it, and the album names disappear. I click on move and it's still there.
I've learned that when you click on the incoming album, if it doesn't show up on the ready-to-move page, nothing happens because you weren't successful in selecting the incoming album. This happens often—five or more times before I'm successful.
