Bug in Check if Users Follow a Playlist endpoint

[soheilpro]

I'm getting inconsistent results when trying to check if a user follows a (public) playlist via the /v1/playlists/{playlist_id}/followers/contains endpoint.

If I follow the playlist via the Spotify apps:

• making the request using my app's access token returns false (which is wrong)
• making the request using the access token that I get from the API console returns true (which is correct)

However, if I follow the playlist via my app first, both access tokens return the correct result.

Here's my code:

curl -X "GET" "https://api.spotify.com/v1/playlists/2hIdQBxY1dQfapPh7ckBQb/followers/contains?ids=1219191128" -H "Accept: application/json" -H "Content-Type: application/json" -H "Authorization: Bearer MY_ACCES_TOKEN"

Just changing the access token, fixes that issue. I'm not sure what's the difference that I get from my app vs. the one that the API console gives me.

You can only check if a user is following a private playlist if you are authorized for the playlist-read-private scope. The difference between the two access tokens is one is authorized for this scope and the other is not.

I'm checking if the user is following a "public" playlist.
