As there is another SIM update going on (SU8) and it is already in public BETA

Sounds promising but for now the FS2020 is a beta cross-platform software with a busy development roadmap planned for years. Each new MSFS update will add new features, fixing old issues, adding new tech issues. Unfortunately many addons will suffer from the floating compatibility issues during that beta stage.

We don't know why some features that work fine on PC, appears to be broken on Xbox. Moreover, MS has put on hold all new releases for Xbox (like the 764), because they perform some Xbox related actions at their end.

For now there's nothing on the Xbox/PC content development difference in the MSFS2020 SDK. So the 777 content for Xbox is identical to the PC one, as per the SDK.

Please do not expect any Xbox specific 777 updates until there's some clear Xbox specific content development difference info in the MSFS SDK.
