Get user's playlist doesn't return followed playlist

[SergeJomon]

Using Spotify API with a personnal app using credentials id and secret authent,

I get different result from the exemple page and my application when getting some user's playlists :

https://developer.spotify.com/documentation/web-api/reference/get-list-users-playlists

I use user-read-private,playlist-read-collaborative,playlist-read-private scopes.

On the demo page, when checking for pierretombal playlists, I get 18 playlist, with his personnal, the one he collab to, and the on he follows.

When doing the same with postman, curl, or my Quarkus app, I only get 4 playlists. Can't figure why. Offset and limit don't change anything
