Irregularities of AdSense Advertisements Delivery, Why smaller 300×250 unit ads are delivered in 336×280 ad unit. Here is why?

For a while, I observed unusual behaviour of my 336 by 280 Ad units, where smaller ads were delivered in 300 by 250 units.

I even reported this issue to the Google AdSense Support Team but received no reply & currently, they are not accepting any new support requests, but how can I get the solution I wanted?

I solved the problem of why smaller unit ads were delivered in bigger ad units, thereby ruining my ‘Website Design Layouts.’

Here is what Google Says about that:

To ensure you are always getting the best results from your ad units, we recently introduced some updates to our ad serving process enabling our larger ad units to serve similar-sized display ads. We’ve already updated this for our 300×600 and 970×90 ad units and now we’ve extended this flexibility to our 336×280 ad unit, allowing it to serve a 300×250 ad when doing so will maximize the performance of that ad unit for the publisher.

With this change you may now occasionally see a 300×250 ad served in your 336×280 ad unit when that unit is opted in to showing image ads. 300×250 and 336×280 image ads will both compete for your 336×280 ad unit with the most competitive ad served thus maximizing the earnings on your ad unit. When a 300×250 image is served it will be centered in the 336×280 ad unit as illustrated below.
