Hello Spotify Developer Team,

I am requesting access to the endpoints `GET /v1/audio-features` and `GET /v1/audio-analysis`
for my app "Cardio-Vélo" (Client ID: 4c407b5bee924e7d9b57f97c7ba61001).

This is a local, non-commercial educational project that analyzes songs to generate
time markers for indoor cycling training. It uses Client Credentials flow and does not
collect or share user data.

I receive consistent 403 Forbidden responses from both endpoints, even with a valid app-only token.
Could you please enable access for my client ID?

Thank you,
Hugo

There is no use, they don't listen to feedback at all... Seems like even Spotify staff is fed up with the change since the original post was edited to bash shareholders:
