Could we add a not supported entry to the Supported Platform Matrix for the Picostation 2? I fell into that trap ordering one off of Ebay not realizing that I needed to look out for that. I have added it to my version at https://docs.google.com/spreadsheets/d/1MN_llh2bHmquKxdD5woZtNpD6RN0s1YrAdZ0s2u8vE0/edit#gid=0.
We've never supported the "non-M" versions. In fact, for the majority of our supported devices, they MUST be "M" versions (ie. M2, M3, M5, M900).
the exception is how Ubiquiti names things like AirGrids, NanoBeams, AirRouter, and a few others. They don't have M's in their name at all.
Only the AirRouter doesn't because it only has one band and my knowledge only comes in equipment hardware of an M series(Ubiquiti did not need to differentiate between new and old )
