Adding the Lead Score field to the Lead Page layout is a necessary step to fix the issue of pilot users not being able to view the Lead Score field on the Lead record page. The Lead Score field is a standard field that shows how likely a lead is to convert based on Einstein's analysis of historical data and predictive factors. The Lead Score field must be added to the Lead Page layout for users to see it on their lead records. Assigning the Einstein Lead Scoring permission set is another necessary step to fix the issue, as it grants users access to view and use Einstein Lead Scoring features, such as Lead Score, Lead Score Insights, and Lead Score Field History Tracking.
