I did check w/ LatinVFR who makes some of these and this was the reply, which looks hopeful if not soon enough:
Hi, we are expecting MS/Asobo fixes the issue with the ILS, presently there is a fix, but its not a definite and complete fix, it will cause other issues. So we aren’t attempting fixing it until the ILS problem is sorted completely, no point in fixing if there will still be issue. We hope in January.
For now please put the ils frequency manually in the aircraft.
