Some people have been having trouble leaving a review on Amazon. I did a little research and discovered that “Written reviews must be at least 20 words and are limited to 5,000 words. The ideal length is 75 to 500 words.” I wish that they had posted that somewhere more prominently. I know that I have left several reviews that said something like “This is great!” Obviously those reviews never got posted.
If you are leaving a review, make sure it is at least 20 words long!
