Tested this on different devices.
Mixer Model: MR18
App Version: 1.0.2 (75)
confirmed on Qu. App shows changes, but the mixer doesn’t. If i touch a changed control in the app, the mixer jumps to that value.
Thanks for the tip. Same on the MR18
Changes are just visible in the app but not updated in the mixer. Just checked it with a 2nd tablet.
