why my kindle app can’t find audible books ? that feature removed?

First, i konw i can free trial 30-day amazon audible . but I encountered a problem: i’m using the IOS version Kindle app. it has an option to “Read & Listen With Audible” in the “more” menu of the library screen, but that just takes me to a list of my books that I haven’t downloaded the audible version of. When I click on a book that I already purchased the audible book for, the button to download and/or play the audidle book is missing. who can help me ?
