Removed all 3rd party mods and tried again. Same problem with both Longitude and PC-24.
ENSB is the only airport i’ve experienced this with thus far. It seems that the default MSFS data still uses the old runway designators, which might be conflicting with your navdata?
I now assume this is the same problem as Missing procedures at ENSB - #2 by NAVData
I guess it works fine in the CRJ due to the dedicated addon package in Hub?
