CLS issue (not passing the Core Web Vitals)

Hello!
I've been having the CLS issue in the last few weeks.
Since it's 0.11, I'm not passing Google's core web vitals test on mobile.
Here's the sample page. You can check it's score in PageSpeed insights.
The problem seems to be <div class="site grid-container container hfeed"> with it's CLS contribution of 0.116.
Here's the screenshot: 
Please help!
Thanks,
Filip
Hi there,
its the advert thats loading later in your hero element that is causing the issue - i made a video recording of the site loading across a slow network:

Those elements listed on your Google PSI report are the ones that are being shifted by the advert.
To fix that give the Container the advert sits inside a minimum height to match that of the advert which looks to be 280px
I've set the minimum height and tried to simulate the loading the same way you did.
Think it's gonna be alright now.
Thanks!
Glad to be of help!
