Thanks for the idea! With data connectors (now Exchange) we typically rely on our partners to choose to integrate and build/maintain the integration. That isn't to say that we can't build an integration that is heavily requested, but it might also be worth submitting this request also on the Google Search equivalent on this forum. Partners can sign up with the Adobe Exchange program here: https://www.adobeexchange.com/experiencecloud.html.
Am I correct that the requested integration is primarily data going out of Adobe Analytics and into Search Ads 360, as opposed to going the other way?
