Hi,
I asked IniBuild about this at the launch and this is what they said:
I find their answer somewhat misleading, the documentation is there and why other aircraft like the 737 is already integrated with the new EFB.
Either they don’t want to do it, or MS has to order this update from them. After that, with their future premium pack where they’ll be updating their aircraft, I suspect they’ll be charging us extra to have versions fully integrated with FS 24.
You can also support the request on this post on the IniBuild forum: Full Integration with the new EFB (follow-up) - Systems - iniBuilds Forum
