PMDG 737-800 Pushback

[Baldeagle53]

The issue is that I have the APU running in accord with the PMDG checklist and when I click on pushback I get a message from GZX to start the APU. Thus, the pushback does not progress as I cannot comply with the message. How do I resolve this?

You posted this in the general discussion forum, so it's not clear if you're using MSFS or P3D.

Have you tried the PMDG Forum to see if there are any suggestions about this issue.
