Authentication w/ Spotify seems broken

[jk2227]

Looks like the backend is following the Authorization Code flow (https://developer.spotify.com/web-api/authorization-guide/) w/ endpoints set up to handle everything but the front end never passes in code/state to the backend and no access token & refresh token is ever stored on the backend, which is making users have to frequently log back into Spotify

I can work with you guys on the backend but I remember @acheng96 said she changed it the way she did to get approved by the app store...
