2012 R2 Hyper-V cluster + SMB 3.0 SOFS share permissions issues

I have a 2 node 2012 R2 guest cluster, both nodes have the Hyper-V role installed on them

I setup CSV

I setup SMB 3.0 SOFS inside the CSV

I'm having a lot of trouble with permissions on the share, i'm unable to create VMs and VHD/X files through the MSCS console or Hyper-V console, getting a lot of permission denied messages randomly.  some of what I see is explained here:

but i'm not sure if this applies to R2, I can't find anything about having the SOFS and Hyper-V roles running on different nodes or poiting to the CSV hard path rather than the UNC share path in Hyper-V:

At first the CSV was setup with ReFS, I rebuilt it with NTFS but it didn't help.

I have made sure that the virtual cluster computer object and the two cluster nodes' computer objects in AD all have full control NTFS permissions on the share, the user i'm administering the cluster with also has full control, sharing permissions are set to Everyone full control as by default when SOFS is created.

I even setup Kerberos delegation which I shouldn't really have to for this stage until I decide to do replication, but it didn't help.

If anyone has done this successfully or can clarify what exactly needs to happen to make it work, please share.
