I work on a site which had really bad CLS scores.
But it wasn’t “real CLS”, it was due to a graph tooltip that showed on hover (which doesn’t count as a user interaction, for good reasons), and followed the user as they panned along the graph.
So I put off fixing it as it wasn’t a priority.

For those monitoring Core Web Vitals, we made a small change to the CrUX History API used by CrUX Vis last night and now return 10 months of data, rather than 6 months of data to bring it more inline with the CrUX Dashboard that we're looking to deprecate. Enjoy!

Awesome #CrUX update by the people from #Google (and also partially available in our free tool as well) 👏
This was added:
→ LCP image subparts
→ LCP resource types
→ Round Trip Time (RTT) tri-bins
→ RTT p75 and histograms
We added #LCP resource type already as well (see attached).
