I’m using their test site since it’s clean and will show the default behavior clearly: https://yucky-yak-mopi.instawp.xyz/event/november-event/

Their support has told me that the default behavior is to offer the patron “save and view cart” or “checkout now,” but this drives the patron to the cart or checkout without letting them add more things to their order. I would like to replace both of those with a simple “add to cart” and keep the patron on the page and close the modal. I can sell the tickets from within WooCommerce, but I like the Tickets interface and want to keep using it (plus selling them from Woo is a bit hacky and requires more steps after creating the tickets).
