Trovelle review for Facebook & Instagram

The app is giving us a temporary error on Facebook when trying to setup checkout on Facebook & Instagram. Facebook support tells us that the bank is not supported. We tried Chase, Wells Fargo and BB&T for payments and all are giving the same temporary error since January. Facebook support is useless and we were told by Shopify support to contact Facebook! Here is the error on the last screen: "A temporary problem occurred when trying to complete your request. Please try again later." This is not acceptable.
