I'm not sure if it's the app or Pixel phones but I can never setup Chromecast or Google speakers using this app or any of my Pixel phones. Instead I have to dig out my old Nexus 6 which does it immediately. What the hell of going on? *Response - I've tried everything you suggested but again, I can't set up newer (or old Chromecast's unless it's on my Nexus 6.... Which does it straight away, target than hanging for ages and running out line my newer Pixel devices.
