This is referring to the MS Store version only.
Just for reference, mine are here:
C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\SystemAppData\wgs\00090000025CC6EC_00000000000000000000000069F80140
In here are a host of GUIDS. For example, the file below contains my Yoke configuration:
"C:\Users\USERNAME\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\SystemAppData\wgs\00090000025CC6EC_00000000000000000000000069F80140\78F01567BD9F4EEB936604788D824EE1\34F1B1D6DA7146FFB88C07082C105720"
If anything went wrong with that sync process, you could always copy the contents of said file, into the contents of the new file, if it ended up being assigned a different GUID.
I’ve never installed it on more than one machine, so I don’t know if these GUIDs persist from machine to machine, but it wouldn’t be much of a sync process if it didn’t.
