I am sure I'm missing a step but why does the MF post Python and new UI send it's config to the WinWing PFP3N even when you are not loading a 3N MF profile in MSFS 2020 and are only loading a MCP profile?
Example, I used to use SimApp Pro to run the 3N for PMDG 738 (when no MF profiles existed for the 3N) and a MF profile for the MCP. Running both SimAppPro and MF in this way worked (even though I know you're not supposed to).
Now, post Python and new UI, even though I don't want to load a MF profile for the 3N and only want to load the MCP, Mobiflight appears in the display and I can no longer use the two system's together
