Seeing an interesting situation at a customer site. Windows 10 Multi-session. Have already done all the standard things, like disable fast reconnect, and turning off gpcalculation on reconnects. Here is what we see, if you repeatedly disconnect and reconnect to your session it works fine to a point. Then you can never reconnect to that session again. It will always generate a new session. Which can be bad, because FSLogix locks your profile and won't work. Doing traces and CDFControl dumps we can see that the VDA session gets marked as invalid, and the guid gets reset to all zeroes. Definitely something with Citrix or MS RDS engine, as we have updated FSLogix, disabled applications running in the image, and WEM. Going to 2402 CU2 seems to get you a couple more reconnections before it fails, but it still fails out. Anyone else seen anything similar?
