Yeah, the weirdness, glitches, bugs and inconsistencies keep piling up across Apple Music/iTunes on iOS devices and Apple Watch, as well as the Podcast app. The latest thing with Music on iOS is that it's no longer syncing between devices. The Apple Watch Music app improved a bit, but it's still a half baked mess (you can't browse an album or playlist until you've started playing it, etc).
In the Podcast app you've got things like episodes force-adding themselves to the tail end of your Up Next list, with no possibility of removing them or changing the playback order... not to mention already played episodes that can't be deleted. It says they've been played and WILL be deleted, but swiping left doesn't work and the Force Touch menu doesn't have an option for trashing them. You have to shift them out of this limbo state by re-adding them, only then can you delete them.
Why this deterioration is happening on many software fronts is anyone's guess, but here's mine: Craig Federighi seems like a really nice guy. A good cop without a bad cop partner. In my experience, software developers don't respond well to nice guys, they exploit them. They're procrastinators who will make up all sorts of BS excuses to not fix certain pesky issues because they're tedious to fix. Not hard, just tedious and lacking in gratification potential. They need a very firm hand, not a total Hitler who will make them hate their job, but someone who makes sure that the path of least resistance is always to fix the problems, even if this requires ensuring that all other paths border on torture.
