I'm following the guideline in https://www.lifewire.com/create-an-audiobook-from-mp3s-in-itunes-2438719 and have a problem with step
Use iTunes to Convert MP3s to an Audiobook
Join multiple MP3s to make your own audiobook
I wanna change multiple mp3 to audiobook. But is not working. Rightclick on selection and "Get Info" -> Options tab ->
music->audiobook from Media kind /dropdown/ and OK. Nothing happens.
It's works by single item well.
