I always start MSFS thru the Xbox App. The drop-down menu always gives me the option to choose the version I want to start, indicating which one I own. In the past this has always been the last choice…MSFS2020 Premium Deluxe Version.
After SU7 GOTY update, it only says I own the Standard Edition, giving me prices for the Deluxe & Premium Deluxe which I already own.
Strange thing is, after the supposed “Standard Edition” starts, I have all of the extra planes and locations that are in the Premium deluxe edition.
