My Question or Issue

When I try to add a song to a playlist shared with me on the web app, it fails (with no visible error except in developer tools):

Spotify sends a POST request to:
https://api.spotify.com/v1/playlists/<playlist_id>/tracks

Payload: {"uris":["spotify:track:<track_id>"]}

The Forbidden response:
{"error":{"status":403,"message":"You cannot add tracks to a playlist you don't own."}}

Adding the same tracks to the same shared playlist on the desktop app works fine. Your permissions are not evaluating correctly on the web app. Are you using different API versions between the web app and the desktop app?

There's 100% a bug here. And it would be nice if the UX indicated that some kind of error occurred. It's strange that the UX decision was to give no feedback about a failure when a user makes a request that the Spotify app fails to fulfill.

I'd like to add that it's SUPER frustrating to have to try to submit this 5 times and fill out the reCAPTCHA over and over (thanks for helping Google farm data from everyone by using their garbage) because you won't accept the topic labels.

For that label selector - if you have a finite list of label options, there's this thing called a DROP DOWN that can communicate that to users. There's this other thing called a MULTI SELECT that lets users choose more than one. I'm not surprised that the UX is about as intuitive here as in the app.
