since page_fans_gender_age will be deprecated on March the 14th, does anyone know about a possible replacement?

Dear all, I am new and use it for Meta Ad Library data. I faced the problem "(#613) Calls to this api have exceeded the rate limit." since last night and it remains for 12 hours. I checked Meta's website, which indicates the rate limit is renewed every hour. So I am quite confused and not sure how I should proceed. Any help is greatly appreciated.

I know plenty of users are experiencing similar issue, but I still didn't manage to understand if we have any solution for it.
I call the conversations endpoint for the Instagram platform, I use Graph API explorer so I have all permissions required.
When I request {pageID}/conversations?platform=instagram, I always have an empty array returned
I even tried with 2 instagram account whose linked Facebook account have a role under the same Facebook page, with no success.
Was there any updates from Meta? Any workaround we can use?

Multiple endpoints seems to return this:
(#3) The API cannot be accessed.
Anyone else experiencing the same? Seems to happen randomly.

We have add the 'business_management' scope on the OAuth2 process as we move from v12 graph API to v17. But users that are not owner of our app still have auth2 dialog that not mentions Businesses. Our users still failed to use pages that are managed by a business account.
Do we need an advanced access to business_management or submit a review to enable this behavior for all users ?
