How to spot CLS issues

Hey guys
For our blog, we seem to pass almost all the time on Core Web Vitals, but the only one that lags is CLS.
How would I find out specifically what the problem is please? As I’m having trouble working it out.
Here is a sample pagespeed analysis for one of our posts: https://pagespeed.web.dev/report?url=https%3A%2F%2Fwww.dreambigtravelfarblog.com%2Fblog%2Fsafetywing-review

We do have ads on our blog, but in this post they aren’t even present. Even if they were there, our ad provider doesn’t really affect CLS.

Thank you for any help or tips in advance! :slight_smile:
