We have a macOS app, SheetPlanner, that supports sharing a document with other people for collaboration, via iCloud Drive. When someone shares a document in Apple Pages, e.g. via email, and someone else clicks the link to open the document, the panel offers to open the document "in Pages", and opens the document directly in the app: But when we do the same with a SheetPlanner document, it is missing the "in SheetPlanner" part, and instead displays the document in the Finder: What are we missing? How can we get the iCloud sharing mechanism to offer to open in the app? Here's a video that demonstrates this: https://dropbox.com/s/bh9ipmn3h9ucpfc/Pages%20V%20SheetPlanner%20Sharing%20Behaviour.mov?dl=0

I have a new app that includes in-app purchases, but the IAPs are not showing up in the app. When testing in the StoreKit sandbox environment, the IAPs are fetched successfully, but when downloaded from the Mac App Store, their identifiers are returned as invalid.One theory; although the documentation says that a developer-specific ID is required, the convention is a reverse DNS format. Could using just short single word identifiers ("sptrial" and "sp1") be a factor?Or could it be a server propagation issue? The IAPs have been approved for a few weeks, and are cleared for sale.
