Yup. Can confirm EDFE is bugged, but only in the first mission.
I tried to set the correct frequencies from the EFB in the radio manually, but the ATC window just says ‘not in use’
There is definitely a problem with the airport data or that mission. Funnily enough, it works in other missions that bring me back to / start in EDFE.
Workaround: Just brute force go without clearance. You can still complete the mission, just the rating will be a bit worse.
On a side note, the frequencies used in the mission are not correct. The EFB ones (in the frequencies tab) are true to life and correct though.
