since v 21.0 metric video_views is abolished. What is alternative?

We are developing an application for an Instagram DM chatbot.
I have a time when the application temporarily stops due to API rate limitation, I would like to know the definition of the number of active users for a graph API request using an app access token.
The formula in the reference is, Calls within one hour = 200 * Number of Users https://developers.facebook.com/docs/graph-api/overview/rate-limiting#application-level-rate-limiting
The Number of Users here refers to the number of daily active users of the app (excluding duplicates). The number of administrator users who are logged in to the chatbot app with FB login Number of general users who actually exchange response data with DM chatbot or other than the above Which of the above applies to you? I don't know the details of the definition and am having trouble developing it.

We have an Instagram posting batch that runs every 10 minutes.
If it checks content_publishing_limit and it exceeds 50, it passes, and if it is below 50, it is published through media, media_publish.
The batch runs every 10 minutes, but usually 5 to 10 posts are published per day.
Even though content_publishing_limit is 0, the following error occurs.
{'error': {'message': 'Application request limit reached', 'type': 'OAuthException', 'is_transient': False, 'code': 4, 'error_subcode': 2207051, 'error_user_title': '행동이 차단되었습니다', 'error_user_msg': 'Instagram은 커뮤니티를 보호하기 위해 특정 활동을 제한합니다. 이 조치가 실수라고 생각하는 경우 저희에게 알려주세요.', 'fbtrace_id': 'ARKi32ke_ey3B-Uvka4AX_q'}}

I am trying to get insights for Instagram follwer_demographics, I get the result but all the responses from the API regardless of timeframe are the same, and the timeframe values are missing in the response.
According to Meta documentation, timeframe is required for demographics-related metrics but I get a response from the API even if I remove the parameter.
Has anyone experienced this issue? How can I solve the issue?

Hello Everyone, I am getting one error again and again when I create the long-life access token using the short-live access token
I am using GET API https://graph.instagram.com/access_token?grant_type=ig_exchange_token&access_token={TOKEN}&client_secret={INSTAGRAM_APP_SECRET}
But getting the below error every time {'error': {'message': 'Unsupported request - method type: get', 'type': 'IGApiException', 'code': 100, 'fbtrace_id': 'Awaqcn7Y2wsavS-DOz6lJu1'}}
Please help me out with this.
