I've had problems with OvrC accuracy/functionality, as well. I would probably have given up on it, except I am a C4 dealer and believe that using any monitoring platform other than OvrC will set me up for headaches down the line.
The strategic commitment that SnapAV has to OvrC is strong. I have to imagine the issues will be flushed out.
If it's not simple, it's not sufficiently advanced.
