Chromecast sample doesn't find any RendererDiscoverer items

I have cloned and run the Chromecast sample made with Xamarin forms. I have tried both branches in the repo. The app is running fine without any errors, but will never find any RendererDiscoverer items. Why is that? I know I have a working wifi and ChromeCast running on my iOS Phone (Chromecast works fine from ex. youtube). I have also tried to set delay to ex. 10 seconds to give more time to discover ChromeCast items, but still no luck. Any ideas to why this is not working. I noticed that the LibVLCSharp Nuget is used in the sample and not the LibVLCSharp.Forms Nuget. I have also tried to switch library and initialise these as mentioned in the documentation.Still no luck. Any advice to get this to work would be appreciated.Thanks
