Please pass along the following information!
If readers can't find our books they can't buy our books!
Instead of showing select mature items in website searches by default, they are hidden by default. If searching in 'All Departments', select mature items do not display. If searching in 'Books' or 'Kindle', in the upper left corner of the display screen it may say "Excluding adult items" and have a "Show all results" link that customers have to click on to see the hidden books. Both of these are in small font and easily missed if you don't know to look for them.
This is not yet effecting all users but it will!!
