Hi,
I usually operate Linda with P3Dv5 without any issue.
I tried the last version of Linda for MSFS2020. I followed carefully your instruction to start it inside the program ( LINDA, MSFS and then connect Fsuipc).
The setting page says that everything is ok but in the window near "Sync to SIM" I get only "Aircraft", but not " MSFS Default" as waited. No way to change it, if I force "Msfs2020 default" as soon I sync to sim the windows return in aircraft.That makes Linda not operating with any default aircraft in FS2020.
It seems like Linda is not able to recognize the list of MSFS default aircraft.
May someone help me please?
