Thank you, thank you, thank you... I've just gone through 3 reinstalls of different version to try and work this problem. Might have been a good idea to start here. :-)
Just confirmed EFIS power on. And the EFIS is running.
This, I think, is a new feature. Beautiful! But ... someone might want to change the checklists to include it. :-)
Is there a place I can report that?
