PlaceHolder text for TextInput is squashed on Android when the TextInput doesn’t have focus. It’s displayed alright when it does have focus. See attached images.
This project was last build end of September 2017, so the whatever causes this must have happened afterwards.
It happens with any that has TextWrapping=“Wrap”. Removing TextWrapping solves the issue (but then wrapping doesn’t work ofcourse. I can live with that in this case :)).
