I am having this same issue on both my iphone and ipad after the IOS update. Unfortunately all the band members had done the update, including myself, and now we can’t adjust any monitors from the stage. We really need a fix for this.
It is showing a connection error when opening the app and trying to connect to the board. The board is on the list so it’s recognizing it’s there but when you click on connect it gives you a connection error.
We have a Qu-32 and love it mainly because of this feature. PLEASE HELP@
