Recently released macOS App: Downloading on the App Store presents "The current version requires OS X 12.0 or later."

I recently updated a macOS catalyst app, using the latest version of Xcode 11. Today, I started hearing reports from users that downloading the app presents an error message:

The current version requires OS X 12.0 or later, but you can download the last compatible version.

This is concerning - anyone trying to download the app is now deterred by an error message. I'm unsure whether I've altered something, or whether it's a problem on the Apple side. It seems 100% reproducible (you can search for 'Class Timetable' on the macOS App Store to see the error message).

Of note, if you browse the App Store listing - compatibility is listed as 'macOS 10.15 or later'. My guess is that the incorrect minimum version is getting used here: the iOS variant of the app does have a minimum version of iOS 12.0, but the Mac App Store seems to be reading this and not the correct macOS minimum version number.

Has anyone else run into this - any suggestions of what it might be/how to get this resolved? I've reached out to Apple but haven't had a full answer yet.

The current version requires OS X 12.0

Any idea why users would see such a comment?

My guess is that there are several compatibility flags on the backend that are being reset right now. Factor in cached info on multiple servers in various locations, and the scene is set.


Current concerns noted, but it might be Friday before things quite down across the board, at the soonest.

The current version requires OS X 12.0

That's surprising. Does it really ask for OSX 12.0 (they now speak of MacOS and 12.0 does not exist (next to come is 11)).

@Claude31 - unfortunately, yeah it really does say that. My best guess is that it's taking the minimum iOS version number (it's a catalyst app) and using it in a macOS context.

@KMT it's not too clear to me... the only way I can explain this is that the iOS minimum version is being incorrectly used in place of the macOS version.

Yeah, hoping this gets resolved on Apple's end somewhere. I guess it's possible there's something that's changed on the macOS binary from my side too though.
Doing some digging... it appears the problem has been around in some form for a while, so it doesn't seem related to the iOS 14 release. What's not clear is what the underlying cause is or how to fix it:

Try searching google for a few values of 'The current version requires OS X <iOS version> or later' too and a few results show up (I can't link them here due to external URL linking rules)
