According to iniBuilds this issue “relates to networking and will affect apps like FSUIPC/vpilot/Simbrief/etc. Essentially, anything that uses simconnect or the networking api.”
Basically, every airplane that connects to an external source should be affected. Fenix is different because it works outside of the sim. Can someone who owns RJ Professional from Just Flight can confirm if this plane is also affected?
It’s been a month since this problem was acknowledged by Asobo and still no fix.
