Hi,
The iFly736 is not an official release for MSFS2024 (only as experimental) and therefore is not currently included in the Hub.
We can add it to the Hub as soon as it is released and we have the official “go” from the iFly devs. Since SU3, there have been a few new requirements for the location of the navdata files (which must be stored in the work folder) to work correctly.
Cheers
Richard
