Guys, I have a client Ive just helped complete a migration (7.15 > 2203). All has gone well but they are having issues publishing IT mgmt apps like Citrix Studio. The pubapp settings look the same between old and new. Only material difference is the old mgmt hosting VDA was 2016 and the new is 2019. They get the following mmc error when launching mmc based apps. We have checked / altered perms and user mode / auth settings on the mmc apps... any ideas? Cheers
