Spotify on Roku won't play

[sambailey79]

I’m trying to use Spotify (app v2.5) on Roku (model 3900EU Roku express, software version 9.0.0) and it all works... except for the ability to press Play! It worked a few days ago. It’s not working now. Nothing has changed in the setup or account.  

I can login (by u/p or by pairing), I can browse, I can add to library. The only thing that doesn’t work is pressing play - on albums, playlists or individual tracks. No feedback or error or response of any kind, it just does nothing when you press play!

I have a free Spotify account (used to be Premium, but downgraded last month - it has worked on Roku as a Free account, with ads, just last week). I’m in the UK.

Things I've tried:

* logged out and back in again (by all the various methods)

* deleted and reinstalled the Spotify app

* rebooted the Roku box

Help!

My tv was perfectly fine yesterday and I played music and then when I send to listen to music this morning no sound comes out and it skips after seconds
