iPhone scrolling problem

Steps to reproduce

  1. Open Dynalist on iPhone (one with 3D Touch)
  2. Open document with enough items to scroll a couple of pages
  3. Click to edit an item with more then one line.
  4. Hard-press on the keyboars and move the cursor up and down.

Expected result

The cursor should move as in any other text field in any other app, but the text itself should remain stationary.

Actual result

Instead, the items scroll around wildly.

Environment

I’m using the Dynalist app for iPhone.
