Since getting my iphone 5c, I've been downloading ibooks (the free ones) and once in a while I have something to say about one of them.

So from what I've been led to believe there is supposed to be a way to write a review on one or more titles and give it a star rating.

However... When I go through all the steps to get to that point, it won't let me enter any information for the actual review. The screen goes blank and the keyboard pops up, but typing doesn't make anything happen! Am I forgetting a step or does the reviewing software simply not support my device?
