Ad Preview & Diagnosis no SERP Data
As of today I'm not seeing any SERP information when using the ad preview and diagnosis tool. It will however, indicate that the ads are visible there's just nothing displayed in the results page area.
Is this is correlation with yesterdays announcement to secure ad search queries or is it just me (very good possibility)

Welcome to the community.
I can assure you this has nothing to do with the latest announcement. It appears to be just you. I'm seeing both paid and organic search results in the tool on 3 different machines and ISPs here (I checked my mobile for you).
Try using a different browser, possibly do the old reliable cache delete or a reboot an see how you get on.
