MuscleFeast review for Warnify Pro Warnings

I purchased this app for Prop 65 warning for 2 products and the setup was easy and straight forward. The only problem is when someone tries to order in California, no warning is populated, so it does not do what it is supposed to do. I would love to upgrade this from 1 star to 5 stars but I have not been able to get any help as when I try to help from their app, I get an error message.
