Hi - I am uploading my app's iOS launch images to appery.io - 8 out of 10 of them upload and store fine, but 2 (Retina 5.5 (1242x2208) iPhone Potrait, and 2x (1536x2008) iPad Portait Without Status Bar) refuse to load. The files seem to upload fine, but when I go back to the image list, they do not appear. If I try to reload them, I get a message about the filename having changed, but they still do not appear.
