I've managed to have my old lay out with side bars back after editing and storing this as "default". App will crash if I touch 1 of the SOF UI buttons in mixer mode.
Also, when starting MS I get a tiny mixer with an overlay of buttons instead of my just created default mixer.
This strange view looks similar as the Edit Layouts screen.
Mixer Model: X32 rack
App Version: 0.064.1 (202)
