1. Go to https://w3c.github.io/web-share/demos/share-files.html. 2. Choose a photo from the device's Photos library. 3. Click "Share". 4. Choose the "Save Image" option in the picker. The problem now is that the share promise never resolves, so the "Share" button can't be clicked again. The share promise should resolve when the "Save Image" option is chosen.
