Sometimes when I am using Accordance with another app in split screen mode, verses will be missing when I scroll through a text. Typically I have an app like Word or Nebo (a note taking app for the Apple Pencil) on 2/3rds of the screen and Accordance on 1/3rd of the screen. In Accordance I normally have 2 translations open (one above the other). When I scroll through one of the texts sometimes a few verses will be skipped. If I scroll up and down several times the missing verses will finally appear.
