Speed Insights deprecates First Input Delay on November 1st - Vercel

Speed Insights is deprecating First Input Delay (FID) and will stop recording new measurements on November 1st.

Speed Insights already uses Interaction to Next Paint (INP) , the Core Web Vital that replaced FID, as the responsiveness metric in your Real Experience Score . The deprecation won’t require changes on your side, affect your score, or prevent you from viewing existing FID data.
