I tried to enable and disable the Facebook <-> Spotify connection again.
It seems that if you disconnects from the Spotify end it works OK, no error messages occur. If you remove Spotify from the list of authorized applications in Facebook then Spotify will not stop complaining about it while the option of disconnecting from the Spotify end is disabled.
I don't know if anyone else has thought about this, but I do believe Spotify may be forcing us to use Facebook by turning off this social feature. If I'm wrong, PLEASE correct me.
Hi everyone- I can assure you users that signed up before our integration with Facebook are not being forced to sign up. You can continue to sign in with your original Spotify username without linking to your FB profile.
Some users that signed up without Facebook have found the following steps helpful (as seen on this thread):
1. Open your Preferences page: Edit > Preferences (in Windows) or Spotify > Preferences (in Mac)
2. Press Connect to Facebook
3. Wait until Facebook login opens and press the Cancel button (if you don't want to link to your Facebook page).
