Yeah, that doesn't help. The shuffle shows up in the finder, but it still won't let me sync the podcasts I want to sync. I've selected the specific shows, told it new episodes only, even created a station that I asked the shuffle to only sync from. It still doesn't sync correctly. .Sometimes, it won't sync anything. Other times. it just randomly chooses podcasts that I didn't select at all. Still others it selects episodes I played weeks ago, can't even find in the podcast app, yet they show up on the shuffle.
When the "Manage Content" button does appear in the Finder window, which is rare, I can finally see everything that's supposedly on the Shuffle, and it's random as ****. It says I deleted it, then that same content gets restored to the shuffle when I click Sync. It's a mess. Apple created this disaster, frankly, because it doesn't care about supporting any product it ever created it no longer sells.
