Same issue here. Managed to complete 2 flights to date but yesterday I was flying KIAD-EGLL and just as I was crossing the Welsh coast all my displays froze and had to give up. I didn’t even interact with the aircraft, all I did was check the destination METAR in the native MSFS EFB. I use MSFS 2024 with the latest SU1 Beta and Navigraph.
Super frustrating, I’ll ground this aircraft until this is fixed but definitely expected more considering how much you charge for it.
