I am trying to implement Facebook login for Business. I have followed the exact same steps in the Quickstart section. I have also tried involking the login flow manually - https://developers.facebook.com/docs/facebook-login/guides/advanced/manual-flow
My app is in live mode.
Nothing seems to work. Please let me know if you had come across something similar.

I have used Facebook Login dialog with the correct permission and gotten access to a person's business accounts. I received a code after the login process and exchanged it using the /oauth/access_token endpoint to receive a system access token (which does not expire).

I now want to get the business IDs of the businesses that the person using the Facebook Login dialog gave me access to, so that I can link their business to mine using the "on behalf of" approach (I'm the partner, they are the client) .

However, for me to do that I require access to their business ID. How do I get that business ID? I know there is an API which returns all business IDs that I (the partenr) has access to, but I want the one that they just gave me access to using the Facebook Login dialog box. How can I do that?

I've tried clearing cache I've use both Edge and Chrome I've used different devices

I am getting duplicate data in my Big Query tables from Google Ads.

I can look at the tables and see rows with the exact same data. Furthermore when I aggregate the data to see total cost of campaigns, it is double what is shown in the Google Ads platform.

I followed the guide for the data transfer and didn't do anything outside the standard set up. I did do a backfill to get data for the entire month because it originally only imported data for the previous week. I also set the date range on the backfill to not include the week of data already imported. And there are duplicates for everyday of the month.

Has anyone experiences this and know why it is making duplicate entries and if so how do I get rid of the duplicates?
