Could anyone please confirm if your callsign and flight number doesn't save again? I am unable to get this to work today, it's calling my tail on a Skywest flight. Wondering if it's me or if they did more server side updates that possibly hosed this functionality again.

No issues here.

Weird. I finished that Skywest flight, went back to the main menu and everything is saving now. 🙄

I doubt it's something that would be touched server side, as when it started happening after SU5, it had to be fixed with a patch.
