Is anyone else still having issues with the tail numbers and hours incrementing? I'd heard the Beta solved it, but not for me, not yet anyway. I've got the same issue with the Baron, the Bonanza and the TBM, haven't checked the Duke yet.
Did you enable the registration numbers with the tablet option? Unfortunately, the Hobbs meter is saves and controlled exclusively by Asobo, so it seems indicative of a broader state saving issue than something with my aircraft.
