Google tests new Featured stores ad design on mobile

Google is testing a new design for the “Featured store” ads section. Previously, this section appeared at the top of the page. In recent days, I have seen it appear below the Shopping ads instead.

Google has also added a “More stores” button to the section. When the SERP first loads, the section shows two to three results. When a user taps the “More stores” button, the section expands to show five to six results.

Here is a screenshot of the design.

I could only see this design on mobile, not on desktop, so I am assuming this test is limited to phones and may not be showing on laptops.
