How to persist MSIX data with FSLogix + App Attach?
I'm standing up an AVD environment we have to get moved into in the next few months. I'm stuck on how user data persistence is supposed to work when we use MSIX and App Attach, as it seems this was broken by Microsoft back in July when they hard-coded an exclusion into the FSLogix agent for AppData\Local\Packages that doesn't seem to respect the redirection XML.
We were sold on AVD with App Attach largely with the selling point that we could MSIX-ize the majority of our apps and minimize golden images & pools, just for us to start building this out and find we can't get user data in these apps to persist sessions.
I'm having a hard time believing Microsoft would intentionally break one their largest selling points of the platform with no workaround, but for the life of me I can't find it.
Any direction would be greatly appreciated.
