FBW A32NX - use flyPad outside aircraft

I have a couple of issues with the flyPad on the FBW A32NX:

  1. The pop-out is not usable in the sense that I can’t interact with it. I can pop it out into its own window, but I cannot click anywhere on its screen to make things happen;

  2. Once popped out, and ignoring issue (1) for a minute, I cannot use the popped out flyPad when I am using an external camera view to control the pushback.

Issue (2) could be related to issue (1) and I’d be grateful if someone could shed some light on these issues.

If you haven’t seen this, this may help.
