Has anyone used the FBW new message system?

The METAR could match… but does it really match with the live weather in the sim? I already set the AOC to use the Meteoblue (MSFS) as a source though. But I’m still not convinced yet.

The reason is that I tried to build a flight with a preset weather. Everything clear, no clouds, no winds, standard barometric pressure and 15 degrees C. But requesting the METAR through the MCDU, gives me the actual current METAR as if it’s on a live weather.
