Sigh*
The A321 does not seem to accept simbrief data from the dispatch add on for the EFB. I suspect theres a conflict between the aircraft and Simbrief and the parameters the A321 has from the drop down menu in Simbrief. So as far as flightplans are concerned the A321 does not compute because the in-game EFB doesnt generate flightplans for this aircraft either.
Was this title even tested prior to launch?!
