Have you tried using manual flight or autopilot selections with a SID or STAR in front of you? You can tune in nav aids and control your heights and distances.
I presume any missing FIXs are new or are unique to fairly recent GPS procedures.
Aero mobile will further improve and is already outstanding.
Manual STAR entry is not difficult.
Totally agree about it being outstanding and continuing to improve. I wish I could merge the mobile flight sim world with the live weather from the one that begins with “I” the scenery and globe/world with the Nav data from the one that begins with “X” and the systems integration of Aerofly-and also use a proper joystick w my iPad as opposed to a game pad-it’s just not the same.
