Hi, I just unpublished my books at Pubit and Smashwords because there just aren't enough sales compared to Amazon to make it worth it. Plus, my book still isn't distributed to places like iBooks through Smashwords. I want to re-enroll the book in KDP select. Is there a time period between my unpublishing at the other places and the ability to enroll in KDP Select? I've gone ahead and asked to enroll, but I wondered if there was a time period before unpublished books were taken off the market?
