Doesn't work most of the time. Just says "Web Vitals are unavailable for this page"

It shows the CLS score. That's a big help.
But WHY the CLS score? That's still a mystery.
The extension should perhaps provide a gif showing the CLS score in a video.
This would be especially useful after an event.
(i.e. suddent jump in CLS after clicking a button)

Goofle Page Insights gave a test page an LCP of 3.1 where as this extension give it a LCP of 0.41 - they cant both be right and as far as Google is concerned it will use it's LCP value not the extensions LCP rating. So for me - this has added a confusion I can do without. I will go back and use page insights rating. Shame as this would have been a great extension. Maybe the dev could add their opinion.

I'm having really weird issues with the extension when it comes to CLS. The scores on PS Insights and Chrome Dev Tools consistently report 0.000 CLS for numerous pages, but when I'm using the plugin and I navigate from search or from one of our pages to another, the initial CLS score is always extremely high despite almost no visual layout shift whatsoever. Then, if you reload the page any number of times, the subsequent scores are always 0.000.

If there is some kind of issue with layout shift that the tool is detecting, I would love to know what it is, but the tool doesn't give you any direction whatsoever as to what elements are causing the layout shift and I can't replicate that score anywhere else, so I have no idea what to fix. In some cases, I've resorted to deleting entire pages on the site and then checking the score with the extension and it will read a crazy high CLS, like 5.74. How can there be such a huge layout shift on a page with no content? Lol. It's really frustrating.

It's just PageInsight API, from Google

This extension is terrific. I wanted a way to measure Cumulative Layout Shifts while toggling different pieces of UI in my page. This was harder to do with some of Chrome's other tools, but the vitals extension made this pretty straight-forward. Great work.
