Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureExpress wallets — Shop Pay, PayPal, Apple Pay, Google Pay — skip your address form, so orders arrive with a street but no house number, or no postal code at all, and the delivery fails. A missing house number only produces a warning at checkout, which the buyer can ignore. This app turns it into a block: checkout cannot be completed until the address is fixed, wallets included.
Some shipping carriers and international fulfillment centers reject orders if the shipping address contains non-Latin or non-English characters. This leads to order delays, cancellations, or refunds, costing your store revenue and customer trust. LatinLock automatically validates shipping addresses at checkout and blocks unsupported characters before the order is placed.
