Since yesterday a very odd thing has suddenly started to happen with the Audible app. I can no longer open any book. Double tapping will start the book playing/pausing but, it remains on the book list screen. So none of the book controls shows up. As far as I know I've not had a recent update to the app so was wondering if anyone else has seen this. As I say only just starting. Hard restart, deleting and downloading again has made no difference. iOS 13.4.1 iPhone 8.
