LCP doesnt report to admin dashboard

Topic summary

A developer upgraded to App Bridge version 4 and switched to the App Bridge CDN via HTML file. Since this migration, their app stopped reporting Largest Contentful Paint (LCP) metrics to the Shopify admin dashboard.

Potential Explanation:

  • Shopify’s web performance data updates within a 28-day window
  • The system may not have collected sufficient data yet for accurate evaluation
  • The missing metrics could be a temporary data collection issue rather than a technical problem

Status: The issue remains unresolved with no confirmed fix, though the suggested explanation points to waiting for Shopify’s data collection cycle to complete.

Hi Harelk1015

Web performance in Shopify will be updated within 28 days. It’s possible that Shopify has not collected enough data yet, so the evaluation may not be accurate. You can read this guide to understand more. https://help.shopify.com/en/manual/online-store/web-performance
