Today, in the desktop app, I tried copying cards from one space to another. I’m not sure what’s happening, but one didn’t make it (and was removed from the original space), and the space the cards were being copied to occasionally gets one of these little blank cards. I’ve deleted it and it comes back, usually after the app says that it loses sync with the server then re-establishes connection. (I’m on a 2.5GB wired ethernet connection.) Is copying stable, or should I avoid it and moving things?
