So, at work I don't have internet, but I have my phone, and I have a chromecast on the tv. I use my phones hotspot all the time for my ipad and laptop with no problem. I have my chromecast setup on my Nexus 5's hotspot as it's internet connection. It works fine if I use my ipad to push content to the chromecast, but on the phone, all apps hide the chromecast option.
So basically the chromecast is invisible to the Nexus 5. I guess because the Nexus 5 is technically the Chromecast's router, and not a fellow client. There are a lot more apps that have chromecast support, so to get this working from my phone would be great. Is there a way?
