Unfortunately their offices are not available due to the current crisis. They can only be contacted via email. They took some logs and sent me a different version to try today but all it did was "Unlock" the option for 160mhz but changed nothing in terms of list of available channels. Since the available channels out of the box were UNII-1 and UNII-2 only i was expecting to see channel 50 adding to that list, but instead all i can see are channels 36, 40, 44, 48, 52, 56, 60, 64.
