Hmm, maybe give it another try if it's been a while.
It's anecdotes, sure, but I do not experience these issues with the App or the Website.
You can Up/Down Vote on your "Radio" stations - but not your custom playlists (which makes sense).
Pandora offers custom playlists, offline listing, unlimited skips of radio, no ads on radio, "hit" playlits (curated by Pandora and other users) and more. It's radio/discovery algorithm is what kept me with Pandora, but all these features make it on-par with Spotify.
