[iOS 26]: Messages “To:” field hidden when sharing via Share #55638
Description
Description
On iOS 26+, using React Native’s built-in Share or react-native-share to share a URL sometimes opens Messages as an embedded sheet and the “To:” field is pushed off-screen. This appears inconsistent and seems related to how UIActivityViewController calculates layout for adaptive sheets.
Steps to reproduce
-
Open a React Native app.
-
Trigger a share using either:
import { Share } from 'react-native';
await Share.share({ url: 'https://example.com' });
import Share from 'react-native-share';
await Share.open({ url: 'https://example.com' });
-
Select Messages from the share sheet.
-
Observe that the “To:” field may be pushed off-screen, sometimes working correctly and sometimes not.
Expected Behavior:
The Messages sheet should always display the “To:” field correctly.
