The Checkout Cancelled screen is a transitional page displayed when the user cancels a Stripe payment checkout before completing it.
This page is shown when the user cancels a Stripe payment checkout and is redirected back to the application. The app records the cancellation in the session manager and then redirects the user to the licence initialisation screen. No user action is required — the redirect happens automatically.
CheckoutParamsManager.setCheckoutCancelled() to flag that the checkout was cancelled so subsequent screens can react accordingly./checkoutcancel route.
