A little clunky...
...In comparison to other browsers but it gets the job done. Have to be sure that the device and the chromecast are on the same wifi for them to communicate. Some of you will think "well, of course!" But for the less tech savvy like myself it's important to know.
Developer Response ,
Thank you for you comment.
I believe that issue will be fixed if you restart or reset your Chromecast Device (reconnect the Wifi network).
The problem is on the Chromecast Device, not the app, so you don't need to redownload the app.
