I frequently get FMC says NO when entering flight plans. Especially at the STARS, SIDS and transitions choices. The information doesn't seem to match up. I understand the problem with airac information- Xplane 11 is 1611 and Simbrief uses 1603 by default but even so the FMC still spits the dummy out. Combine that with ATC and ATIS info not agreeing within Xplane and also not matching to real life when real weather is chosen is frustrating. Will there be a sort out-out to iron out the FMC, airac, real-world and plate info?
