11% of these page views were in-app (soft) navigations. Those report INP and CLS, but browsers only measure LCP, FCP and TTFB on full page loads, so those three cover fewer page views.
What to fix first
Slow page loads cost you engagement
Comparing like with like (the same page type), page views whose main content took over 4 s got 61% less engaged time and 76% fewer clicks than ones that loaded in under 2.5 s. Based on 115 slow page views across 5 page types.

Does speed cost engagement?
Page views grouped by their own LCP. If slower pages get fewer clicks and less reading, that's the cost of slowness.
