In current version of the app, you can cancel or suspend subscription payments only through website or directly in an app of a specific subscription service. We are working to provide users with this functionality eight in the app in near future .
In order to disable or cancel a subscription in the Subty profile, you need to go to "Subscription Management" screen, where you can edit the subscription, make it inactive, and delete it. To do this, simply click on the desired subscription, and in "Manage Subscription" screen, select "Make inactive" button. Your subscription will move to the inactive section of "My Subscriptions" menu.
