Well the MS Store I have not had an issue downloading either updates or games that I had previously purchased before Windows ARM. I have added one or two free games but don't believe I attempted to purchase any games you have to purchase (either through the Store or xbox app) till these issues get resolved. I did purchase a trial of the Game Pass for PC (think it was only $1.00 a month for the first two or three months) just to see if these games would work on my M1 iMac under Parallels. But as we all know, can't download anything yet from the Xbox app. Still keeping fingers crossed.
