Hello, need examples, please

We didn't make any layout changes, so I presume it's an advertisement that messed something up?
Ads are always dynamic - so we'll need not only the screenshot, where it leads you to (cos we're not programming them; it's from an external provider), as well as the device and browser used.
At the point of posting this, I've not seen any anomaly on my end, which is likely because I've not been served the ad you've seen.
Cheers!
