I stopped using Vero4K with Spotify. It is simply not stable, sometimes need to reboot the device to see it appear in Spotify on my phone. It is also extremely annoying you cannot stop the playback in OSMC to watch something. It’s been over a year and there is no priority to add Spotify Connect to OSMC officially, even after lots of requests.
I can no longer recommend this method of manually installing it, only for experimental purposes since it is not well integrated and does not give you the simple install once and use forever experience.
I am switching soon to using the Vero4K purely Al’s a playback device for video and absolutely nothing else, even though it has plenty of resources to do more… Not sure if the future will bring more, but the waiting is over for me.
