In the middle of listening to music it appears that scrobbling has gone down. I'm on PC and Android and both don't seem to be able to access the API.
I appear to be having an issue too. On my iOS app, it's logged me out, and when I log back in, it takes me to the screen where you connect the application/authorize it, and when I click "Yes, allow access," it just goes into a loop pulling the same screen up over and over. :(
