What version do you have?
I uninstall and reinstall in content manager.
V1.2 for 500/700 and 1.3 for 900/1000.
No update available in content manager at this time.
I reaload the aircraft and now seems format/range buttons are working.
In 700 variant EFB is set in cold and dark default state, in 1000 is set to Ready for start as default state .
I will try a flight on monday. Im out of home this weekend.
