Seeing Error When Modifying Cart Quantity Totals

Just upgraded JigoShop to latest version. Went to test and found it no longer lets me increase or decrease cart item quantities which previously did work.

Looked in console and I see this error each time I adjust quantity:

Uncaught TypeError: e.block is not a function

I have deleted all caches since the upgrade of Jigo. I’ve logged out of WordPress to view the site as a normal user also.
