I know there is no way to decrease the crown rotation' sensitivity using WatchKit (only through SwiftUI). But is there a way to deactivate it completely while using the app? The issue is that users keep touching it by mistake, making the screen scroll too far.
There is not
For anyone stumbling around here, in my particular case, I had a WKInterfacePicker that could be controlled through screen touch or crown rotation. To ignore the latter, I used an inherited method:
override func pickerDidFocus(_ picker: WKInterfacePicker) {
picker.resignFocus()
}
