Hi Tully,
Thanks for the notification. I have cancelled your Pathfinder Adventure Path subscription. You should get an email that confirms this change to your account.
The main reason that we do not just have a cancel button on the My Subscriptions page is so that we can maintain a level of human interaction with our customers and fans, especially if the they have feedback they would like to share with us.
Additionally, when a subscription is being cancelled, we like to make sure that system actually does what is supposed to do and that the cancellation processes correctly.
If you have any further questions or concerns, please let us know.
Thanks!
Sharaya
