Intermittent. The expected behavior is for the calculation to happen automatically after the address is entered.\n\n## Simulation\n\n1. Open a cart with any products in it.\n2. Go to the address step and enter an address (e.g. \"Avenida la Marina, 2400, San Miguel, Peru\").\n3. Click the shipping cost calculation button — nothing is calculated, the button is only highlighted.\n4. Click the button again — the calculation runs.\nIf the button works on the first click, leave the checkout flow and come back to checkout: the button then stops doing the validation it was doing before.\n\n## Workaround\n\nN/A"}
