I just noticed, when you finish playing an item on the new downloads, it’s marked as played… But on the library it came from, it always displays as there are X Minutes left, not marked as fully played.
Also, with the old syncs, you could browse the main library, and when you play something synced, it would play synced item instead of streaming it from the server.
With downloads, even if it’s marked as downloaded, if I play it from the main library, it always streams it. You need to go to the downloads library to play the downloaded ones instead.
