I'm running into a consistent sync issue between my mac and my iphone, when playing through my iphone. The desktop app seems to lose sync so that even when I pause playback on my phone, the desktop app shows the progress bar continuing to climb and the pause button doesn't swap for a play button.
I moved the app to trash and redownloaded and saw the same thing.
Note that I can send pause+skip requests from the desktop app but cannot resume (again, button doesn't swap with "play" button)
