CAPs and 911G-2HPnD

I could have sworn 911G supported CAPs, but when I try to configure it, I get and error:
“Couldn’t change CAP - license does not allow CAP mode (6)”
Is that accurate, or just a bogus error message because of some code issue?

RouterOS v6.49.1 (stable)

Is correct. RB911 has RouterOS licence Level 3. You need Level 4 o higher.

Regards.
