[KDP REJECTION] Why Did KDP Reject My Book & Said That My Book is Not Low Content

When you publish a "medium content" book, like a coloring book, activity book or puzzle book and you had check the box saying it is low content, is it not actually.

Generally what they do and the email will say, is they have unchecked the "low content" checkbox and all you have to do is click publish again for it to be approved.

If they did not uncheck the box for you, then you need to and then publish it.
