So basically.
I select max flex for take off, then when notified on the screen I select LVR BLB mode and sometimes everything works but other times I need to keep the throttle at Max flex for the entire climb which then seems to sort itself i.e LVR CLB mode works almost 100% once I am at my cruise altitude.
On the first initial start up 60-70% of the time I need to reset the flight due to, usually the map screen being blanked out for both, the 787 mod and both the DEV A32nx and the stable build
