So, with the pre-launch, it is a one-time charge. The accounts are supposed to show a "cancel" button, but they aren't due to it being a one-time charge.😡 I am working with my IT guy on this today and tomorrow. I know this is really frustrating, but I launched EcchiART rather quickly and this is some of the downfall of that.
Once it is working you can cancel the membership, as all of those that are on the Pre-Launch will be moved to the subscription (what I am doing now). Then the cancellation will be available from inside the account.
