How to stop Google Ads to shift / blink my mobile AMP pages while loading?

I have implemented AMP via WordPress AMP plugin and theme that supports AMP version. I have spent much time on shaping this theme to look how I want it to look, but I have one problem I do not even know where to start fixing it, it possibly could be something easy.

I am using Auto Ads and Auto AMP Ads, however on desktop version, or non AMP version of the site, I don’t see the problem, while loading an AMP mobile version makes site (page) to shift / blink layout, and only when Google Kit is enabled (when google ads are present).

I know I have to fix it with CSS, or something similar, to stop google ads resizing page.

For me it looks like AdSense loads its CSS before my page loads its CSS, and blinks few times until everything is solved and page shows as it should, but this is pretty annoying and I wish to fix it if it is possible.

Please can someone check: https://mllapan.com/ and point me how to fix this behavior. This is behavior on mobile load (video): https://streamable.com/u95b9d
