The app stopped syncing after the last update and support took a week to reply. We lost orders during the outage and had to switch to a competitor.

About Zvanta Address Validator
Wrong or incomplete delivery addresses cause returns, support tickets and refunds. Zvanta Address Validator checks every order in checkout — including express and wallet checkouts — and stops undeliverable addresses before the order is placed. After purchase it verifies addresses against official postal registers, shows the customer a ready correction and can fix clear errors automatically. It never changes an address it is not sure about. Every rule ships with a recommended default.
