really having issues running / getting music features for this app I am making need help

[ToxicFame]

App client_id: 74f865b2e21a4b849c60492d534ce0a7
App status: Development mode
Endpoint /v1/me works (200), but /v1/audio-features/{id} returns 403
for both user tokens and client credentials tokens.
Example track: 4uLU6hMCjMI75M1A2tKUQC

This happens consistently across curl, Postman, and Python requests. Any idea how I can get this to work I've been stuck on this for like 16 hours and its making me really sad.

Hi @ToxicFame 

Thanks for reaching out.

That endpoint has been deprecated, meaning this can't be used by apps anymore.

Note: some old apps may still be able to use this endpoint.

I hope this clears things up.
