There’s a thread in this community from September that hasn’t been answered and I’m experiencing the same issues:
Whenever I add any of the scopes from the Music API, it tells me they’re all invalid and it won’t give me an Access Token.
Is there anything special I need to do?
Hi Brett,
This error message suggests that your LWA application Id is not safelisted for API access. We are keeping track of your request and will let you know if we will be able to add you to the beta. If by chance we can’t add you to the beta, keep an eye out on our site and for an email as we hope to expand this to non beta users early 2025.
