Channels for Prime are Back in the Audible Apps, YMMV
Audible.com introduced Channels for Prime several years back for Prime members for free, but early last year they scaled it back, removed it from the Audible app and moved some of the contents under Audible shows and they were very difficult to find.
Now it seems the Channels for Prime are back for both the Android app and the iOS app (oddly, I still couldn't find the option in the Audible app for Samsung S8, even though the app version was the same).
And better yet, there is a new section (new to me) under Channels for Prime called "Audiobook Collections". You can stream from 50+ titles (no downloading), some of the titles are listed below:
H is for Hawk
The Secret Adversary
The Zookeeper's Wife
Seal Team Six
