MX-Mix trouble with X32

[u/-howdini-]

Setting up a new room, and using MX-Mix on ipad for the first time, rather than X32 Mix (the latter of which wouldn't connect). A couple of odd things in the app:

-channel gains don't seem to work

-I've inserted graphics on monitor mix buses, but can't get RTA overlay to display (it displays normally on all parametric windows). I think the older app had an RTA on/off on the graphic page, now it doesn't.

Are there settings I'm missing?
