Firstly, both my desktop app and mobile device's app, I can't see any button under the Social that "Connect with Facebook". (I will send my spotify settings page and also my username) I checked my facebook, and i can see my spotify account in there, i allowed it and also i logged in spofity with my facebook account. My username is still seems to be as random numbers and letters.
Please help me.
