If you select (or if the only option) ‘local pickup’ in the checkout shipping section and the Date Input and or Text Input fields are used, the checkout process shows an error requesting a shipping address to continue, but there is no shipping? If the fields are removed, then all is OK.
I have v17.2 installed and still get the same shipping required error for local pickup.
This happens with the plugin activated and with fields or no fields used. It is forcing you to check the ‘Ship to a Different Address’ check box and fill out the other shipping address.
If you deactivate the plugin the order goes through OK.
