Natural Hair Rules
I was using this app to deliver mix goods (a physical & digital product). At first, it worked perfectly. Customers could download digital good immediately after a successful checkout while they were waiting fulfillment of their physical item as described in the app's documentation.
From App's Documentation
"Customers will still be able to immediately download the digital content even if fulfillment is set to manual. They are presented a link following a successful checkout."
All of a sudden it stop delivering a download URL following successful checkout. I contacted Shopify Support and I was told that the above Reminder was an inconsistency and that the app is not supposed to function that way at all. Which I still can't understand because it functioned in the way described in the App's Documentation for months. Shopify Support and the App's Developer confirmed that the Documentation that describes this functionality is an "unknown error". I guess they're happy that I reported it.
