Ever since 10/4 we have been receiving random failures with several ad related endpoints, primarily campaigns and ad sets. The request failure is the same every time: “Unsupported post request. Object with ID ‘act_xxx’ does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api”. We are using the v20 api but have also tried v21. For example, requests to /act_xxx/campaigns with the following body:

{
  "name": "newtest2",
  "lifetime_budget": "30000",
  "objective": "OUTCOME_SALES",
  "buying_type": "AUCTION",
  "status": "PAUSED",
  "special_ad_categories": "[]",
  "bid_strategy": "LOWEST_COST_WITHOUT_CAP",
  "start_time": "2024-10-10T20:30:00-0700",
  "end_time": "2024-10-12T17:30:00-0700"
}

will succeed 4 times and create a campaign, and then will fail with that error. The type is GraphMethodException, error code is 100, and subcode is 33. Has anyone encountered this before or have any ideas of what we should change?
