When using FS2020 the frequency is not active (white letters). If I use P3D all is fine.
I am using Prosim 737 and CPFlight radios and I must use FSUIPC in Prosim. If I use Simconnect in Prosim, the frequency e.g. 128.125 shows 128.120 in vPilot and that cannot be use.
There is no issues to log into vPilot, only the letters are white and then I cannot use voice on Vatsim
