Adsense AMP Auto Ads Not Showing

A week ago, while trying Site Optimization process, something happened and the site stopped showing auto ads on Amp pages and Desktop. I installed few plugins for speed optimization like W3cache, and few others (unfortunately i don’t remember them now).
The site uses WP Rocket and Heart beat plugins. It also has DISQUS and a plugin called “DISQUS conditional Load”. When i uninstalled DISQUS and DISQUS conditional load the problem began.
I tried to check in browser console, it gave an error message , "A cookie associated with a cross-site resource at google was set without the SameSite attribute. A future release of Chrome will only deliver cookies with cross-site requests if they are set with SameSite=None and Secure. "

I tried to figure out the cookie but all in vein. Can you please help in resolving the problem?
The site url is myksa and a page
