[Use as Home Share] SMB option missing after upgrade from Fangtooth to Goldeye

I have a setup with TrueNas storing roaming profiles for Windows AD. I set up a share [users] and selected purpose as “Private SMB Data and Shares”, set up ACLs and checked “Use as Home Share”, path suffix %U
I set up Documents folder redirection to \\truenas\%username%\Documents and so on.

It all worked perfectly until I upgraded to Goldeye - the shares are no longer accessible this way, and I can’t see option “Use as Home Share” in SMB advanced properties.

Was it removed, or is it now a different way to set it up? I can reconfigure profile paths if I have to, but I would rathen keep it as is. As an alternative I could map user profile as a drive letter and reconfigure AD to use it. Is there any other way to minimize disruption?
