Is anyone using the Google CMP solution given in Adsense? I have tested this feature out on a few sites, and what I noticed is that those sites turn "insecure" in my browser afterwards.

I thought it was an issue of mixed content. But it can't be, as those sites were made secure a looong time ago.

Then I noticed ONLY those site with this Google CMP feature were affected, the rest not on it were all secure.

This is very baffling, and I wonder if anyone had the same issue or noticed the same issue.

By the way, even after activating this Google CMP, I am unable to see it in action. There is simply nothing on display. I am guessing because I am not in the EU region and Google detects my location and thus will not show the banner/notice?
