I cannot create a device password. I requested one on Spotify and got an email. I followed the email and all I get is a very non-specific error message: 

Oh no!
Something has gone wrong! But don't be sad.
You can try again a little bit later.

This error message is no help at all. This has also been going on for at least 12 hours for me (which in my opinion is a "little bit later"). I've tried creating a password through Facebook (Settings > Security > App Passwords) but the password generated does not work and does not let me log in using the generated numeric username or my email address. I'm using the Chrome browser. I've also tried to do all these steps through an Incognito Window in Chrome and nothing works. Really looking for a solution here. When I pay for a "premium" service I expect all the components to work properly.
