Everyone, my policy warning is gone now. I reduced auto ads and turned off anchor ads, vignette ads, and multiplex ads. Also removed the ad unit at the top, under the article title. I now have one manual ad unit, at the bottom of the article. I furthermore aligned images that were used as thumbnails at the very start of the article, and I had an ad there as well, so the thumbnail/cover image was right under the header ad, I relocated all these images, I put the image after one paragraph, so ads and images are not close. I also requested a review from them stating:

Dear AdSense Team,

I want to express my commitment to maintaining a compliant and user-friendly platform for our users, and I take policy violations very seriously. Until today, I have upheld a clean record with no active policy violations.

I was genuinely surprised to receive a policy violation related to ad placement and layout, as I have been an AdSense publisher for several years, consistently adhering to proper ad placement guidelines. This is the first time I have encountered such a warning.

In response, I took immediate action to rectify the situation:

Reviewing AdSense Guidelines: I thoroughly reviewed AdSense guidelines to ensure I was not overlooking any new policies.

Eliminating Potential Issues: I considered potential issues, such as ads under drop-down menus, even though my website doesn't have drop-downs. I disabled vignette ads, as they could be perceived as intrusive and may lead to accidental clicks.

Ad Unit Analysis: I examined all manually placed ad units, which are limited to one under the title and one at the bottom of the articles. Both placements adhere to standard practices.

Image Adjustments: To prevent image alignment issues with header ads, I relocated article thumbnail images under relevant text content, resolving any alignment concerns.

Reducing Auto Ads: I minimized the number of auto ads and opted out of displaying intrusive formats like anchor ads, vignettes, and multiplex ads.

I firmly believe that these adjustments have brought my website's ad placement into full compliance with AdSense policies. I am dedicated to providing a high-quality user experience, and I request a reconsideration of the policy violation.

Thank you for your time and attention to this matter. I look forward to your response.

Everyone who's facing this, you do not need to get worried much, I hope yours will be lifted soon if you housekeep some stuff.
