Could this be an Android (6.0.1) specific issue?
I have been using UC Surface on my droid tablet for a few years without issue, running a 16.4.2 AI board. I purchased a 16r mixer a few weeks ago and updated my UC Surface software to 3.x (April 2019 release). Now, when I edit any Fat Channel parameter, the "edit popup window" appears and will NOT go away once I make my edit and lift my finger off the tablet. If I touch ANYWHERE on the tablet the value will change to something totally random and the edit popup window goes away. You can imagine how frustrating this is when trying to set an EQ during sound check!! It does this in DEMO mode, and on both my 16.4.2ai and 16r mixers....it's definitely a UC Surface issue in this new release.
Anyone experience this on an iPad, by chance?
