I encountered an issue while updating an ad creative using the Facebook Graph API. The ad creative initially contains two videos with associated asset_customization_rules. I tried to update the same ad creative by adding a third video and its asset_customization_rule via a POST request.

The POST request returns a success response, but when I retrieve the ad creative using a GET request, it still returns the older data without the newly added video and asset_customization_rule.

Steps to Reproduce:

Create an ad creative with two videos and their associated asset_customization_rules. Use the Facebook Graph API to update the existing ad creative by adding a third video and a new asset_customization_rule. Receive a success response from the POST request. Perform a GET request to retrieve the updated ad creative. Expected Behavior: The GET request should return the ad creative with the updated list of videos and their respective asset_customization_rules, including the newly added video.

Actual Behavior: The GET request only returns the original data, without the third video and asset_customization_rule added during the POST request.

Additional Information: The issue seems related to updating the asset_customization_rules for an existing ad creative.

Please investigate and advise on how to resolve this issue.
