We noticed ours did the same thing a few months back after an update on Roku but like the first poster, today more options are missing and there has been no new update. The app is fine on our phones and computers. I'm kind of bummed and hope it's resolved soon.
Re: Roku Spotify app: Playlists not an option anymore (playlists gone)
Playing my music through the roku makes a big difference for my tech set up in my apt, and yes, without a real spotify option through roku, i may just switch back to pandora and/or at least cancel my spotify premium account.
*AND - even when I just try to play certain artists - the option to play ALL their music is GONE - and I have to choose just ONE album at a time.
SO NO GOOD
There's no reason it shouldn't be able to offer all the same things it does via computer.
