Hello,
During testing of the checkout process on our WooCommerce store, I encountered an issue with the checkout form.
When a customer enters their billing details, including the address, the system displays an error when submitting the order stating that the address needs to be entered, even though the “Address” field has been properly filled in.
The address field is highlighted in red and displays a message indicating that the address needs to be entered.
Interestingly, when the customer checks the “Ship to a different address” option, thereby activating the form for a separate shipping address, the order can then be successfully submitted.
Therefore, the issue occurs only when using the primary billing address, even though the address field has been properly completed.
