Stamped Reviews & Loyalty

Warning: After using the reviews app only, I switched to a full year plan of Full Suite (Loyalty and Reviews) with Stamped. The loyalty portion did not work, with an obscure explanation that it would work when I was migrated to their new Loyalty 2.0 (despite the fact I had just signed up). They refunded me, and I returned to working with Smile for Loyalty. Since then (April 19), Stamped is no longer sending review events to Smile, despite the apps being configured correctly. I have escalated service tickets in for over 5 business days with no solution.
