My 4520 for the last two days, after many attempts, will only come up with a response of "empty" when I ask for my playlists. I'm in touch with "spotify cares" on facebook, but they don't seem to have any idea why, their latest question was whether my firmware was up to date (which it is), so wonder maybe it's like Denon's issue with the Pandora app changes in the past?
I've reset my modem several times as well as a soft reset on the 4520. It usually takes a couple minutes for the playlists to load, and just once in a while before this I'd get this "empty" message fairly quickly as I'm getting now, but would pull up the playlists the next attempt, but this is the first time it's been persistent. My Onkyo's Spotify app has always pulled up the playlists quickly, and is still doing so.
Anyone else having such issues?
