Apogee ONE with Djay

Hi there,
Is there anyway to setup Apogee ONE with Djay so the pre-queing works?

When I plug my ONE in to the lightning hub and headphones into iPad headphone jack the djay settings come up and I choose ONE as main output and headphones for pre-queing but only sound comes through headphones for pre-queing even though I can see level meters are active on ONE.

It’s only when I unplug headphones that sound comes through Apogee ONE output again. Is there something I’m missing?

Thanks,
Mark

I figured it out… needed to download Maestro app on iPad because when I connected headphones on iPad it muted input to Maestro so I needed to unmute input to ONE using Maestro app on iPad.
