When I run the search "rick ross net worth" the featured snippet is an article from theexchange.africa. When I open the link on mobile, there are no ads shown.
If instead I search "in: theexchange.africa rick ross net worth", the top result is still the same article but not as a featured snippet. When I open on it on mobile, there are ads showing.
My question is: Why would the mobile ads only show in the second scenario and not the first despite both linking to the same article?
I have set up Auto AMP Ads for theexchange.africa. If I visit an article directly from it's link (eg. https://theexchange.africa/africa-billionaires/michiel-le-roux/) the ads show as expected.
Now since site visitors are more likely to get to the articles from a Google search, I went ahead and did the search described above. For some reason, if the article is accessed from a regular search result, the ads show up, but if accessed from a featured snippet then the ads don't show.
Could it have something to do with the content being served from https://theexchange-africa.cdn.ampproject.org?
