Right with you, AlexAppleUser: the Shuffle is perfect for books, and fiddling with them on an iPhone in the car is just plain dangerous. I hope Apple is paying attention to our frustrated cries for help.
After upgrading to Catalina, my various Shuffles were simply not recognized in Music or on my MacBook, so the Podcast drag-and-drop work-arounds I read about here can't work for me. All kinds of checking gave no fixes, so I backtracked to Mojave. (A saga in itself: Time machine bombed, but luckily I had a Carbon Clone Copier image from May; at least I have my books-on-Shuffle back, even if I lost some files in between.)
Apple's bland "try this, try that" answers are simply not helpful. I would like the issue to be acknowledged, even if there is no fix right away. Failing that, my long-time trust in Apple - also since 2005, as it happens - remains badly damaged. I am already spreading warnings to think twice about accepting upgrades unquestioningly, and if there is no resolution in this case, in effect abandoning loyal users unwarned, I shall be tempted to go back to Windows.
