I have an Apple touch icon included on a website that renders fine on the iPhone when selecting “Add to Home Screen”, but when selecting…
- Add to Reading List
- Add Bookmark
- Add to Favorites
…no preview image gets displayed (or added).
My meta tags specify an image for “apple-touch-icon.png” and for “apple-touch-icon-180x180.png”.
Why would the preview for “Add to Home Screen” render the image properly, but not for the other 3 options above?
