Scaler 3 iOS does not work with apple pencil pro

With apple pencil on my iPad Pro M4 I cannot do the following with apple pencil

  • Select multiple chords
  • Arrange page move position slider
  • Arrange page exten position slider handles from either side
  • Mixer adjust volume
  • Mixer adjust pan
  • Adjust height of B Current scale section
  • Adjust height of C Main track keyboard section

Pretty much anything you do with a pencil besides tap doesn’t work. Everything springs/jumps back to original location on release
