The progress bar will get to ~80%, then the entire CoC2 window (except the bar at the top with the app icon/title and the minimise/maximise/close buttons) goes white. It isn't a device-related issue, as it was working just fine yesterday (i.e. before the most recent public update; I'm not a backer, if that's relevant) and playing in-browser on the same device (which is a laptop, not an Android) loads just fine.
