Unable to retrieve the “views” insights metric using Instagram Login

I cannot retrieve the "views" metric for media using Instagram Login (graph.instagram.com), but I can retrieve other metrics such as "likes."
On the other hand, I can retrieve the "views" metric when using Facebook Login.
As of version 22.0, my understanding is that the "views" metric can be retrieved using both Instagram Login and Facebook Login. Could this be a bug?
The error code is as follows:
// https://graph.instagram.com/v22.0/:media_id/insights?access_token={{access_token}}&metric=views
"error": {
"message": "Instagram Insights Media API endpoint does not support the metrics: views. Please refer to https://developers.facebook.com/docs/instagram/reference/media#insights for more details.",
"type": "IGApiException",
"code": 100,
