Apple Arcade on Mac not using family sharing, but works fine on iPhones and iPads.

I have family sharing on our Apple account, shared with me, my wife, and our son. Everything works fine all of our devices, except for Apple Arcade on the Macs.

This ONLY applies to Apple Arcade on the Mac. Everything else with sharing works on our Macs (News, Music, App subscriptions). They can all be shared fine. But when someone tries to download an Apple Arcade game on the Mac, it says it needs a subscription. Everything else though, through the regular App Store works fine and they can download shared purchases.

Apple Arcade works fine on their iPhones and iPads. This is ONLY FOR THE MAC, and ONLY FOR APPLE ARCADE. I can't stress this enough. All other purchases and subscriptions work fine on all our family sharing Macs.
