I am using the A2A Comanche on Xbox X. Recently there has been an update and A2A say it has made its way to the marketplace now. The latest version is 1.6.5 I think.
In the develpment blog update from Oct 15th the Comanche is listed in the “Updated” category for MSFS2020 as “updated on PC and Xbox.
Hi @FrankO7109
Anytime users have issues with marketplace products not appearing in their my-library or my-hangar, they should contact the Zendesk & open a ticket. Other users on the forums obviously have no access to your marketplace account & so really cannot help determine what is wrong, other than to provide comments such as “me too” or “OK on my PC”.
