For anyone that installed FS2020 thru Steam and are having trouble with the A320 update, hopefully this will work for you as it did for me. I tried several times dropping the A32NX into the Community folder but to no avail. After some trial and error, it finally worked after putting it into: Steam Library/Steamapps/Common/MicrosoftFlightSimulator/PublishedPackages folder. Might not work for everyone but it works perfectly for me now. It also worked for the DR-400. Hope this helps someone. Cheers, Gary
