Hi,

I'm receiving 4xx errors when trying to fetch my client's data such as top 50 tracks and Spotify recommendations, although the authorization process is valid, the user accepted all the required scopes, and the user is registered in my Spotify dashboard.

Note - this issue does not occur for other clients.

Hi @Asaf_Krenzler, welcome to the community. Which 4xx series status code(s) are you seeing?
