Had a good chat with support this morning but I wanted to post the summary here for further attention.
We launched our new site last month which includes services as monthly subscriptions.
Turns out that, when a customer cancels, we must manually change their subscription status to pending or some other status in order to generate/export a list of active subscriptions to fill at the next fulfillment date.
That we must do that manually is clumsy at best. Should a cancellation email get missed/ not get to us, we still would process that order for the next month's fulfillment date.
There is currently no way to view in the orders panel/export ACTIVE subscriptions - unless as I say above, we first have MANUALLY changed the order status of any cancelled order seems to me that would be a very important feature. I cannot imagine a much larger business with hundreds of subscriptions doing this manually.
