My Question or Issue

All my Sonos speakers have disappeared from Spotify connect on my iPhone. They are visible on my iPad though! 
I've tried deleting and reinstalling the app, resetting my router and Sonos speakers and even erasing my iPhone all to no avail. 

I can use the sonos speakers on my iPad and android phone on the same account. My wife and daughter can see them on their iPhones and iPads. I logged into my daughter's account on my iPhone and still could not see the Sonos speakers. 

The problem is only on my iPhone, but I have no idea how to resolve it, as erasing the phone and restoring from backup did not solve the issue. 

Anyone got any ideas?

Thanks, Russ
