Hi Fabian,
It turns out there are some subtleties to how
AdGroupAd change events are stored that lead to the creation event appearing with status
CHANGED. I'm discussing this further with the change status team, but could you let me know how you're using the status so I understand how the current behavior negatively impacts your use case?
Thanks,
Josh, Google Ads API Team
