Whether you see a direct Cancel Subscription button or have to submit a Request to cancel depends on two settings the business controls together: a site-wide default (Config, tab "Order: Subscription", "Show Cancel button on profile") and a rule set on your specific subscription ("Cancellation": Not allowed / Request only / Self-service, shown on the subscription's admin record). Whichever of the two is stricter wins. Only when both allow self-service do you get the instant Cancel Subscription button, which immediately turns off auto-renewal and marks the subscription as cancelled. If either is set to "request only," you get the Request flow instead (staff review and cancel it for you); if either is "not allowed"/"Client cannot Cancel Subscription," no cancel option shows at all. A direct cancellation can't be undone from your side once it's done — you'd need to start a new subscription if you change your mind.
