UPDs not working with Elastic Layering and SoFS

I have a Server 2012R2 image setup for Elastic Layering. The layering works ok, but if I enable User Profile Disks, I can only place them on a standard SMB share. If I put them on my Scale-out File Server, the UPDs are mounted and created, but the OS fails to write to the profile and doesn't unmount them on logout. I have to power off the server VM in order for the lock to be released. I use the same SoFS for a Win10 VDI NP managed pool with UPDs, and it works just fine. I can't find any report issues with Server 2012R2 and SoFS with UPD -- in fact, that is Microsoft's recommended method for UPD HA.

I'm running Unidesk 4.0.8 with matching client tools version, in a Hyper-V environment. I've rebuilt the image from scratch multiple times, with nothing layered in the image. I can reproduce it reliably. UPD on single SMB = works ok. UPD on SoFS = locked, no data written, no matter how the share is configured (CA on or off). UPD + Win10 + SoFS = works ok.

Server 2012 has no issues by itself storing UPDs on SoFS, and neither do my VDI pools. Is this configuration not supported?

Or is it that UPDs don't work at all with elastic layering? Turning them on causes the server to never release the UPD on logoff and then a temporary profile is created every subequent logon until the server is powered off. If I don't assign any applications to elastic layering, then there are no UPD lock problems.
