We have identified an issue on Google Pixel C devices where users are seeing an error message when trying to watch videos on our app. This is caused by the correct cookies not being passed to the app in order to play videos, and so the video fails.
This issue can be resolved by completing a factory reset of your device. You'll find the steps to do this on Google's support site here: https://support.google.com/pixel/answer/6328687?hl=en
