I use my Wiim Pro to stream music between my PC music library and my Marantz AV10, and it works quite well. Except for one frustration: if I change files or folders on the PC, the changes don't appear on the iPhone app that controls the Wiim, at least not right away. For instance, a week ago I moved a folder within Music on the PC to a different folder, but on the app it still shows as having not been moved. And, I carelessly deleted a playlist two days ago, but even after restoring it, it still isn't on the app. I'm thinking the data is being cached somewhere, but I don't have a clue. Any help folks?
