Chrome Dev Tools experience section in performance tab not working

Question

Question regarding - https://developers.google.com/web/updates/2020/05/devtools#cls

I was trying to test this feature using beta 84 and dev 85.

For me - experience section never appeared in performance tab. What can be the issue?

Answer 1

Today I had the same issue in Chrome on MacOS. After enabling "Layout Shift Regions" in "more tools" "rendering" and then doing a profiling in performance tab, the experience session appeared below the timings section, but only if relevant layout shift events exist.
