Unexpected behavior change in /campaigns/ endpoint

Hi,
Since around January 18th we’ve noticed that the endpoint
GET https://backstage.taboola.com/backstage/api/1.0/{account_id}/campaigns/
has started returning campaigns for network accounts.

However, the documentation states that calling this endpoint with a network account should always return 0 results:
https://developers.taboola.com/backstage-api/reference/get-all-campaigns

Can you confirm whether this behavior has changed intentionally?

Thank you
