This is a known issue at various airports and does not mean that ILS is not available into the sim/aircraft. You can participate there:
ILS RWY 34 is available:
ILS RWY 16 is available:
ILS RWY 14 & 28 are available too.
Could you test again on your side if you can receive the ILS ?
Did you test with your community folder empty ?
Moved to User Support Hub ATC, Traffic & NAVAIDs until more users can provide feedback about receiving or not ILS at LSZH.
