I just discovered while attempting to find and download an ill-behaving Mac game there was another Library listed iPhone & iPad Apps as well as Mac Games. I was able to download a favorite iPhone game, at no cost as I had already purchased it on the iPhone, and it plays perfectly on my M1 Mac. the Display is identical but blessedly larger on the Mac display. The number of available apps is limited mostly games at this point, but I am confident that will expand.
