Web browser support: expo-sharing for web is built on top of the Web Share API, which still has very limited browser support. Be sure to check that the API can be used before calling it by using Sharing.isAvailableAsync().

HTTPS required on web: The Web Share API is only available on web when the page is served over https. Run your app with expo start --https to enable it.

No local file sharing on web: Sharing local files by URI works on iOS and Android, but not on web. You cannot share local files on web by URI you will need to upload them somewhere and share that URI.
