Steps to reproduce
Use Dynalist for a while, then press up or down arrow keys.
Cursor moves to next line / previous line.
Cursor moves to start of line / end of line.
Windows 10 app 1.1.2
The problem goes away when I close and restart Dynalist. I don’t know what triggers it.
This seems similar to iPad Smart Keyboard Arrow Keys Don’t Work, but I get this on Windows Desktop.
