Same problem with 3 computers running Windows 10 Pro x64 b15063.11 with Fences 2.13 and 3.03
Can change Portal view to "details" but not remembered on reboot.
Really like the v3 feature of being able to navigate within the Portal without the file manager opening but that also reverts to icon view.
It would also me nice if Portal would remember when columns have been re-arranged, I prefer Name + Size + Date order, but that's never worked.
Looks like Fences needs a small tweak.
