WVD Windows 10 multisession and MSIX

So we're attempting to setup MSIX and as such downloaded the insider program image as the instructions said and created a VHD from it that I uploaded to an azure storage space and created a WVD host from. I havent finished setting up the MSIX app attach stuff but i noticed i can only log into the host 1 person at a time, subsequent connections to it knock off the existing connection. Is there no way to have windows 10 multisession and MSIX app attach? Is there something i need to do to the image?
