Mobile LCP of 6-7 seconds. Server response of 72ms. The problem was a scroll animation hiding our primary heading at opacity 0 until JavaScript hydrated. Here is what we found and how we fixed it. The numbers did not add upWe ran Lighthouse on the Stackra.app homepage. Desktop performance scored 94. Mobile scored 63, with a Largest Contentful Paint of over 6 seconds. Our server response time was 72 milliseconds. A fast server response rules out the backend. The delay was happening in the browser
