Sorry for the late response, been a bit busy. Do you have the project code somewhere online (like github) where I could look at it? It’s a bit hard to debug your case with this information alone.

What you could try to see if it has to do with the element itself or the styling would be to write inline css into the component. Anything simple like a background colour should to.
<View style={{ backgroundColor: ‘#ff7100’}}>…</View>
(mind the ‘ ‘ copied from here. Those are probably not valid as this is a rich text editor)
