Do I need a second subscription

I have a current subscription for P3D Do I need a second one for MSFS 2020

Hi…,

Welcome.

No, your current subscription covers both .

Cheers

thanks I could not see how to add it so I just created another one for PMDG with a custom location to the path where the data needed to go. It seems to be there

For MSFS 2020 make sure you use the Navigraph Navdata Center

Cheers
Ian
