Apple Arcade games won't load on Mac
I am running Catalina on a 2014 iMac. I am signed up to Apple Arcade and it works for myself on the Apple TV, iPad and iPhone.
However, on my iMac, I am able to download the Games but they will not play under my account. However they work for my family if they log onto the same Mac using their accounts. I am an Admin on the Mac so it isn't a permissions issue.
If anyone has any suggestions, I would be very grateful.
The link below shows what happens if I attempt to Launch an Apple Arcade game logged onto my Mac as myself.
