I have the permissions public_profile, email, pages_read_engagement, instagram_basic, instagram_manage_insights, pages_show_list, read_insights, and business_management. When I make a request to the API https://graph.facebook.com/v19.0/{your-user-id}/accounts?access_token={user-access-token} using a user ID and user access token, I sometimes get account data for some users, but for others, I receive empty data.

I encountered this issue before adding the business_management permission. After adding that permission, everything worked fine, but starting yesterday, users have been notifying me that they can't get account info.
