Can't log in with Facebook with Spotify included as authorized in Facebook app page

[RickBiker]

Although Spotify has connected with Facebook and it shows as authorized in Facebook's app page, at Spotify user's general configs, Facebook show as not connected, by still showing "connect with Facebook". See links

I use different emails to connect with Spotify and Facebook, but when I firstly clicked to "connect to Facebook" it proceeded ok.So, I do not think it has the 'two account effect'.

Now it's not connecting to Facebook any longer. When clicking again "connect to Facebook", Spotify user config page has been showing for some time: "Sorry, a temporary error occured. Please try again later.

HELP? Thoughts? Thanks!
