I’ll just try again with another suggestion.
In April 2024, runways 14/32 were changed to 13/31 but It seems that this still hasn’t been implemented in Beyond ATC.
Until recently, the flight schedule was still working, but the wrong (old) runway was being cleared.
My last attempt to fly from EDDK a few days ago ended with an error message stating that the departure (using runway 13L) was invalid. So BeyondATC and EDDK are still not compatible.
When will this finally be fixed?

You are probably using the free SimBrief planner, which is still on the old AIRAC cycle and doesn’t reflect the updated EDDK runway changes. The runways were renamed from 14/32 to 13/31 in April 2024. Because of this mismatch, flight plans may appear valid in SimBrief, but BeyondATC rejects them or clears for the old runways. Hopefully BeyondATC will eventually make flight planning possible without relying on SimBrief.
