Hi,

Safari Technology Preview: Release 115 (Safari 14.1, WebKit 15611.1.3.5)
Both Ad Click Attribution and Ad Click Attribution Debug Mode Experimental Features are enabled.

Different domains used for publisher and advertiser & publisher with the following tag included:
<a href="https://click.advertiser.example?pid=3" adcampaignid="52" addestination="https://advertiser.example" target="_blank"><img src="https://ad.example/creative_1.png" alt="click now!"></a>

As explained here: https://webkit.org/blog/8943/privacy-preserving-ad-click-attribution-for-the-web/ I expect to see the logs when using: log stream -info | grep AdClickAttribution

No other errors or warnings are shown in the Web Inspector

Thanks for filing, please attach a reduced test case in the form of an HTML, codepen etc.

What happens if you drop the target="_blank" attribute?

Hi,

After enabling/disabling the features & restarting several times, logs are working as expected now, so I'm going to close the ticket.

Thanks!

Hi John,

My bad, forget the previous comment.
Removing the target="_blank" attribute did the trick and now it works.

Not sure if that's by design, but I'm reopening as using target="_blank" shouldn't be a privacy concern.

Thanks,
