I am trying to organize my homepage tiles with shortcuts to the sites I frequent most. Some sites have their logo automatically appear in the tiles, for other websites it does not. For those that the logo does not appear automatically, I edit the tile and select "Use a custom image" Upon entering the URL, the image appears in the preview, but once I save, the tiles appears blank (just a white square). Any suggestions on what I can do? Ive tried various images for various tiles - it appears as soon as I try to add a custom one it goes blank (see screen shot as example)
