I have required "updated" permissions as per this document - https://developers.facebook.com/docs/instagram-platform/instagram-graph-api/reference/ig-user/insights#requirements
"instagram_business_basic" and "instagram_business_manage_insights"
But I am still unable to get insights for the testing Instagram account. - Instagram account is linked to Facebook account - Have added instagram account as tester in app
Any help would be much appreciated.

I am using Instagram API with Instagram Login and have live(not testing) app. I got enough scopes. When I use "https://graph.instagram.com/{instagram_id}/tags" endpoint, I can get tagged media in some accounts but others get 400 status code and this error {"error":{"message":"Unsupported request - method type: get","type":"IGApiException","code":100,"fbtrace_id":"AJeSMqmb-9xrcVdqxJ9xf3L"}}
I cannot find difference between accounts which can get tagged media and other accounts that cannot get tagged media.
I need help.

Hi Facebook Support,
We have an Active App with "instagram_manage_messages", "instagram_basic" permissions, we are providing custom inbox solutions on the behalf of our clients.
Since last week, our access token are receiving "App not active".
Could you please advice if this is our Application's issue? From the error we are not sure what to do exactly to rectify this issue.
Our Active Application App ID: 211928969883126
Appreciate your help.
Regards

tried logging in using instagram fb page. to gain the message responses on an api. Continuously shows empty array

I have both instagram_business_basic and instagram_business_manage_comments permissions reviewed and live on my app. However, the username field is still not available in the API response.
According to the documentation on the username field, it should be accessible with the instagram_business_manage_comments permission, but that doesn’t seem to be the case.
Is there an additional step required to enable this field, or is this a known issue?
