So, as I deactivated my Facebook account briefly and revoked access to Facebook from the apps page (https://www.spotify.com/tw/account/apps/), my Spotify username turned to numbers. That's normal and it has happened to me before when I previously deactivated. However, when I activated my Facebook account and connected it to my Spotify Account again, my name did not return and there's no longer an option to revoke access (or restore access, for that matter) to Facebook. There is also no longer anything under the Social heading under settings in the app.
What steps should I take in order to return my Spotify name to my Facebook name?
