After a fairly successful use of the trial I bought the android app but its constantly losing the connection to the chromecast.

e.g.

I start the app and start streaming a video but then none of the controls work. I go back to the device list and the device has disappeared, hit refresh and it appears again. But after the refresh the controls still dont work and I have no way of stopping whats playing on the chromecast apart from using another app to change or reboot the stick.

Any tips on fixing / debugging this or providing you with more info to work out why?

thanks.
