INP got 17% worse than the previous 24h
p75 INP is now 220 ms. The Vitals tab shows when it changed and which pages it changed on.

Visitors in DE wait a long time for the first byte
p75 TTFB is 1.83 s for 13 page loads from DE (10% of page views), against 640 ms in KR. Most of the time goes on waiting for the server.
Try: The server takes long to start sending the page: cache the HTML (at the CDN if you can) or speed up the code and database queries behind it.

Mobile visitors get a much slower LCP
p75 LCP is 2.64 s on mobile against 1.53 s on desktop. Mobile is 53% of your page views.
Try: Test on a real mid-range phone or with CPU throttling: big images, heavy JavaScript and third-party scripts cost far more there.
