Can't open the share dialog in iOS with React Native

I'm developing an app using React Native and I have the following piece of code:

Share.share({
  title,
  message: url,
  url,
})
.then((a) => console.warn('', a)
.catch((e) => console.warn('error', e)));

This works fine in Android but in iOS the share dialog open up and closes instantly, while my app keeps freezed, as if it were waiting for some response from the share dialog.

Any idea? Couldn't find any issue related.

This is what I'm using: https://facebook.github.io/react-native/docs/share.html

I've also tried ActionSheetIOS and I get the same behaviour.
