So we had pretty good luck with Sage 100 2020 Advanced as a Published App in Windows Virtual Desktop (will be pooled) in that we didn't get any of those reported errors, but the users do get a "Record '' is missing from SY_Workstation" (error 11 below) sometimes on first start. If they immediately try again, they get in and can work. We played around with the ClientName, SessionName, ComputerName environmental variables but it didn't make a difference. It feels like a timing issue to me, so we're going to experiment with some delays and also try full Published Desktops to see if that causes any changes.
Next up, we're testing Sage 100 Standard to see how performance is.

We're actually in the middle of spinning up a pooled WVD for Sage 100 Adv and haven't had any issues yet. I'll report any findings in a few days.
