My Question or Issue

How can I disable the very annoying popups that appears after changing the device? (Spotify Connect).

For example, I have a Tablet running Spotify, that act as a controller for my Cambridge Audio network player and shows what's playing. And another on my desk. Nice! 

However, if I then "grab" the audio, say to my mobile or PC, then the a big popup appears on all of the devices stating "You are listening on (insert whatever device I am using)" I have to go and close the popup to see those display again. 

I see no purpose to these invasive popups. It's not that they disappear after a few seconds either. They stay until I close the popups.

How do I disable these? Frankly, it ruins the nice information displays that I was hoping for.

Thanks.
