Premium, United States, Spotify version 8.6.94.351 // iPhone 8, OS 15.1 (19B74) // Mac OS Big Sur Version 11.5.2 // Google Chrome 97.0.4692.71 (Official Build) (x86_64)

Here is what Spotify says:

(1) Connect your Spotify account to Facebook
Note: You can only connect your Spotify account to Facebook using the desktop app.

(2) In the desktop app, click [down arrow] and select Settings.

(3) Under Social, click CONNECT WITH FACEBOOK.
Enter your Facebook login details and click Log In.

I would love to do that, except that under Social, there is no "CONNECT WITH FACEBOOK" either on desktop, browser, or mobile. There is also no visible option to connect to either a Google account or an Apple account, either.

Right now I cannot link to anything and have been frustrated for a couple hours to the point where I'm thinking I probably just have to create an entirely new account to connect socials or alternate logins.
