My Question or Issue

API to check if current user is following artist returns inconsistent results. If I'm running it from my local env (from Poland), it returns correct results, however if I run same request with the same token, it returns incorrect results that don't reflect the actual situation.

Example curl:

curl --request GET \
  --url 'https://api.spotify.com/v1/me/following/contains?type=artist&ids=2ye2Wgw4gimLv2eAKyk1NB%2C6mdiAmATAx73kdxrNrnlao' \
  --header 'Authorization: Bearer 1POdFZRZbvb...qqillRxMr2z'

Response from my local env (Poland) which corresponds to actual state. The API calls from this location reflect the changes immediately.

[true, true]

Same curl running on one of our backend instances in US, always returns incorrect result and it doesn't change regardless if I follow or unfollow the artist.

Our APP is still in development mode and has the following scopes:

• "user-follow-read",
• "playlist-read-private",
• "user-library-read"
