Anyone else having trouble with MBraille crashing on the latest iOS 12.4 when reviewing text by word?

Hi
After updating to iOS 12.4, when I use MBraille's in-app keyboard and want to review text that I've written word by word (holding down dot 3 and swiping), the app crashes and deletes all the text I've written. Is anyone else having this issue?
I'm using iOS 12.4 with an iPhone XR, smart layout, danish uncontracted braille.

Best
