Thank you for the feedback. There is a lot to digest there but I'll leave a few comments below on a few points.
With regards to the aircraft loading in, there are some known issues with WASM compiling in MSFS 2024 as well as an issue with the latest Navigraph 2412 navdata that can cause displays not the power on. This is covered in point 1 of the following FAQ as well as some workarounds: https://support.justflight.com/en/support/solutions/articles/17000143831-rj-professional-msfs-2024-known-issues
The file directory for flight plans is different in MSFS 2024 compared to the previous simulator:
MSFS 2020 – Microsoft Store:
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages\justflight-aircraft-rj\work\JustFlight\FlightPlans
MSFS 2020 – Steam:
C:\Users\USERNAME\AppData\Roaming\Microsoft Flight Simulator\Packages\justflight-aircraft-rj\work\JustFlight\FlightPlans
MSFS 2024 – Microsoft Store:
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.Limitless_8wekyb3d8bbwe\LocalState\WASM\MSFS2020\justflight-aircraft-rj\work\JustFlight\FlightPlans
MSFS 2024 – Steam:
C:\Users\USERNAME\AppData\Roaming\Microsoft Flight Simulator 2024\WASM\MSFS2020\justflight-aircraft-rj\work\JustFlight\FlightPlans
The three RJ Professional manuals have also been updated with the v0.1.2 update to include various minor differences between 2020 and 2024 file directories:
RJ Professional Operations Manual
RJ Professional EFB Manual
GNLU-910A FMS Operations Manual
We'll continue to monitor feedback for the other points you have mentioned, and apply any necessary fixes in the upcoming updates to the RJ Professional.
