Can I skip an upcoming shipment for my subscriber?
Absolutely. In the Conjured Subscriptions dashboard, find your subscriber by searching for them on the View > Subscribers page. Click on the subscriber and select the Upcoming Shipments tab, which will list all the upcoming shipments that the subscriber has along with the date they're scheduled.
Hover over the upcoming shipment and click the "Manage Shipment" button. From there, you'll be able to skip or unskip the shipment, and edit the scheduled shipment date.
