I recently bought PHNL and though it shows installed on the Inibuilds site and is in my Community folder (MSFS2020) however in the sim when started it is not present - just the generic from MSFS phnl.
I have exchanged many communications with support and it has not been fixable. My last comm to them was about a week ago.
In my last comm to them I told them i simply give up and they can keep the money paid.
I am a long term customer.
