ghost boxes in sonos favourites in ios app

 Can you do this?

unfortunately not. upon hitting edit there is no minus next button next to the ghosts. I’ve tried deleting and reinstalling app. nothing shifts them.

That’s really odd (and thanks for the screenshot!) 

I’d try a couple of things. First, I’d attempt a network refresh. Unplug your Sonos from power (or power down, if it is a battery driven speaker, it should be off), and then reboot the router. Wait two minutes, then plug back in the Sonos devices. Wait another two minutes, then open your controller and see if the ‘ghost’ items are still there.

If they are, then I suspect you’re going to need to call Sonos Support to discuss it. You may need to get through the Chatbot to speak to a representative directly.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Does an App Reset clear that sort of thing? Fast and pretty painless, I'd try it before calling in.

Which content service were the stations saved from and is that service still installed?

I am assuming TuneIn or Apple Music. Neither of which are still attached services. Removed them ages ago.

 Seems like that should not be necessary.  When you drop a service those Favorites should just disappear.
