@Dave-Pilot2ATC - I think some of those options have changed in SU5.
A bigger problem I have now with MSFS 2020 is that Pilot2ATC no longer seems to recognise my squawk code. I set the code, then click Ident, but when I check in, the controller keeps asking me to set the squawk code that is already set. This was fine prior to SU5.
Because of this, I can no longer complete a flight with Pilot2ATC and MSFS 2020.
Not Pilot2ATC's fault, I know - just one of the many things broken with SU5, but I thought you should know in case you didn't already 😀
Ah well, back to X-Plane where it works flawlessly!
