Pictures stored in your Magpie account did not load in the mobile app: the app sent the request without your sign-in, so it was refused. This affected your profile photo in More and Account settings, image library thumbnails, contact photos, chat pictures, document pictures, store product images and the image pickers in QR Codes, Favicons and Image Converter. These now load.
If your profile photo cannot be loaded, the app shows your initial instead of an empty circle.
