Hello! Welcome back to the forum!
Hmm, does any of the other Navigraph features work - such as showing charts or SimBrief import?`
If not, then there is nothing we can do about this - Cerenado has intentionally disabled the loading of global plugins. In this scenario, Cerenado needs to either reach out to us for a custom plugin that they include with the aircraft, or they need to allow global plugins to affect their instruments.
Apologies for the inconvenience!
Kind Regards,
Malte
