C4 hub and I'm on 188.8.131.52 and not sure if I did something or missed reading release notes?
Refresh/remove/routes were never available with the old z-wave stack that is used on the C-3/C-4/C-5. They are only available with the new stack for the C-7 and C-8.
So what you're seeing is normal.
Duh, thanks Aaiyar. Come to think of it I don't recall ever having issues with Z-wave on the C4, guess that's why i thought it changed.
