"Place-Order" Button Breaking on Order Forms (looks like Keap may have fixed this now)

Since Saturday our order forms are nonfunctional due to what appears to be a JavaScript error on Keap’s end. JS script is requiring a variable to be present that is missing: ‘tagname’ . The js code that runs the place-order button is breaking due to that error. Anyone else experiencing this?
