IPhone app doesn't refresh "New Music"

Hi everybody!

I'm using the Squeezebox app on an iPhone 4. When I add new music to the library and check via the browser interface it shows on the server under "New Music" as it should. When I look in "New Music" on the phone, it doesn't show. I can still search for it or access it via the music directory and it plays fine, but I quite like the "New Music" function. Any ideas?

Info: Recently I've updated to iOS 6, but the problem prevailed.

Thanks a lot in advance.
