Unlimited review asks for the Review Request app. After a paid sale, your buyer gets one Whop message with your review link. Pro removes the 10-per-month cap on the free plan. Nothing else changes.

Install the free app first: https://whop.com/apps/review-request-app
Pro only lifts the cap. If the app is not installed, buying this does nothing.

No feature is held back. Pro exists because sending more messages costs more, not because the free tier was crippled on purpose. If ten asks a month covers you, stay on free and keep the $7.
