Our billing/delivery addresses don’t look right on order received page, looking at woocommerce docs they show it side by side which would look much better, hopefully the link attached sends you there.
GP doesn’t interfere with the Woocommerce CSS on the order received page – that would be Woo’s code. I had a nose and there isn’t any CSS that should display the layout any other way then it already is.
Can you link to the example where its displayed in columns – and ill see what we can do.
