[WP 7.5] FB Login Approval feature breaks Spotify Windows Phone Mango App

[harel]

This took me a while to figure out, so I figure I would post it here as a heads up to other users and hopefully the Spotify/FB team can fix this.

If you have FB Login Approval feature (Under Account Settings --> Security) enabled, you will not be able to play any songs in Spotify for WinPhone if logged in via your Facebook acount. The solution is to either shut off Login Approvals on FB, or log in to Spotify for WinPhone using plain Spotify credentials.
