When using the Papa John's UK app, after placing an order, customers are presented with a screen that encourages them to join a monthly partner program for 15 pounds/month. The placement of the "Continue" button next to the statement "Your order is complete" may lead customers to inadvertently sign up for the subscription without fully understanding the implications. This design pattern deviates from the typical use of a "Continue" button, which would typically lead to a summary page.
