I am calling the instagram API to authenticate like described here.
So I am calling (with correct instagram-app-id and redirect-uri):
https://api.instagram.com/oauth/authorize
?client_id={instagram-app-id}
&redirect_uri={redirect-uri}
&scope=user_profile,user_media
&response_type=code
But I get the following error/response:
{"error_type": "OAuthException", "code": 400, "error_message": "Cannot access app due to app restrictions"}
I got the necessary instagram_graph_user_profile and instagram_graph_user_media permission approved (via App Review for Instagram Basic Display).
I can not find anything regarding this "app restrictions" error. I have no app restrictions set up. What could possibly cause this error?
