Now it don't. For some reason YouTube casting from chrome works fine, but no other tabs. It just says "can't find any cast units".
Any ideas? I have tried to reinstall and followed the google troubleshooting. I can't cast from my ipad either. Is there any way to restart the inbuilt chromecast?
There's the Cast Receiver app. Try manually force stopping and starting the app, or uninstall and sideload an earlier version from when it did work.
