Hooray! Disney+ is finally out and with some great content too. We don't really know why you'd want to cancel, but maybe you binge watched everything before your trial ended or you just weren't that into The Mandalorian. In that case, maybe it would be wise to cancel until some new amazing content comes out (which we're positive will happen). If you've made the decision to cancel Disney+, here is how you do it:
From your PlayStation console
Log into the PSN account which purchased the subscription.
Click on Settings, Account Management, Account Information, and then PlayStation Network Services.
