Still problems with the new version.

There were major problems with the first iOS7 version of ProPresenter Remote when trying to control ProPresenter 4 (slides wouldn’t show up). Now the slides will show up (finally) but you can’t switch playlists. Well, you can if you’re okay with only being able to control the second slide in your playlist. Seems to work okay if you only attempt to control a the first playlist you access, although I haven’t tested it extensively yet.
