dLive MixPad for IEM mixes

Hi everyone!

Currently setting up a dLive CDM48 and CTi1500, previously I've only used the Midas M31 so this is quite a big step up... doing okay so far, we have the in-ear mixes set up right and going to all the right places. But i'd like to get the monitors set up on the iPad using the MixPad app and eventually OneMix so that each band member can have their own login, but I cannot figure out how to actually adjust faders for each in-ear mix on MixPad.

I watched some tutorials and people have set up a different User account on MixPad just to use for monitors, but I can't even get that far? One tutorial just said open up MixPad and go to "Users" but that's not even an option on my screen here.

I already have Mixing Station so for now we can use that, but I'd love to get up and running on the more "official" app.

If anyone has any tips or advice for using MixPad I'd really appreciate it! I tried to find a manual for it but couldn't seem to locate that on the Allen and Heath website.

Thanks!
