On the calendar breakdown, navy blue designates days you’ve read, while the lighter blue shows days you haven’t. Days without a color haven’t yet been computed and haven’t been accounted for.

The Please share. . . box isn’t for reporting bugs and glitches in the app. Kindle for iOS has its own reporting form elsewhere. If you chose later to not submit a bug or glitch or would like to start over, press the < in the top left corner.
