🌐Review Passed but the App Isn't on the App Store — Setting App Availability After the Fact via the App Store Connect API
TEI Scanner, which I had submitted to the Mac App Store, passed review but never appeared on the App Store — instead showing 'removed from sale'. The cause: App Availability had never been set. This is a record of diagnosing the symptom with the App Store Connect API and setting availability after the fact via the v2 appAvailabilities endpoint.
