Thanks for letting us know. Can you please provide the following info so I can look into having these ads investigated?
1.What device and browser/OS you're using.
2. Your general geographical location.
3.The URL of the ad, you can get this by right clicking the ad and clicking "copy link address". You can also click "inspect" and copy the highlighted text.
4. Screenshot
Once received, I'd be happy to send it to our ad team so they can work to have these pop-ups blocked.
Cheers,
Erik
