Why won't my cover save? It just keeps spinning and saying to wait.

Make sure your photo is not too large (should be under 4000 pixels in width/height). Also, the sytem cannot recognize non-English letters or symbols such as hearts from a mobile device keyboard. Do not use keyboard shortcuts to type in other alphabets (Cyrillic, Hebrew, Arabic) or to add accent marks not typical to the English alphabet. If you are using Safari, try using Chrome or Firefox.
