While you wait for better answers, it might be useful to try to see if the problem persists with current versions of things, especially since you’re using obsolete beta versions at the moment.

I have updated stable 4.0.0 / 4.0.1 / 4.0.2 / 4.0.3 version in app but facing same issue in (Iphone / Ipad) real device and emulator both

I have updated 4.11.5 latest version but app still not running in real device / emulator

Referance : https://www.npmjs.com/package/@ionic/angular

This is emulator screen for

<ion-input></ion-input>
