I have just downloaded the latest update for the client. I had over 100 songs on my iPhone waiting to scrobble. After syncing and waiting over an hour for it to scorbble I gave up and did it manually through the diagnostics function. Guess what, it only found 1 track, and that was one I hadn't listened to on my iPhone.
Seriously, how can this still not be working?? It's the one thing that is preventing me buying a subscription, but the service is useless to me as I only listen to tracks on my iPhone.
