I upgraded my phone to WP8.1 and updated all the apps. Spotify would not go "online", even though under Settings it was set to be online. I toggled that a few times to no avail. So I uninstalled the app, rebooted the phone, and re-installed the app.

Now when I launch the app, I get the splash screen, and hit "Login here". I enter my username and password and hit the "log in" button, and wait. And wait. And wait. Nothing.

While connected to Wifi and using a packet sniffer, I see the TCP three-way handshake occur to apresolve.gslb.spotify.com (193.182.8.112) port 80, and then nothing. The app never submits an HTTP request. To me this suggests a problem with the app, rather than a server-side problem that wil get resolved.

I see a similar behavior when not connected to wifi, though I can't verify packet traces.

I have uninstalled and re-installed the app several times, generally rebooting the phone in between.

Anybody else seen/seeing this problem? Any suggested fixes or workarounds?
