Riskified

I'm getting more concerned using this app now due to an order that was prior approved then being declined after shipment. The app allows for users to update addresses to check to make sure the new address is safe. Well I had an international customer that I couldn't confirm the out of country address so I asked them for another and I input that info just to check with Shopify's shipping label address check to see if that would change the address status and Riskified delined even though I switched back to the original approved address for that order. It makes me wonder how many shipments I've sent out that won't be covered. Now they won't cover their initial approval of the address that I actually shipped to.
