Your bad LCP score might be a backend issue

"LCP score issues often stem from backend problems that aren't immediately apparent. To identify the root cause of slow LCP scores, developers can use tracing to track the complete end-to-end user journey across all downstream systems and services. This involves installing an Application Performance Monitoring (APM) tool like Sentry, collecting data from real users, exploring Core Web Vitals scores, finding sampled page load events with poor LCP scores, and then exploring the full trace of those events to discover performance bottlenecks."
