Description: Choosing Custom instructions on the Cancellation tab in Retention Management shows customers who want to cancel the instructions you write for them, instead of a cancel button.
From your customers' end, when they click to cancel a subscription in their customer portal, they see a window with the message you wrote in the field above.
As you can see, there is no cancel button in this window, only a Close button, so customers need to reach out to you to cancel. For the full setup, see Cancellations and retention offers in Appstle Subscriptions.
