Absolutely bug ridden and terrible app. Xfinity doesn't seem to care about fixing the bugs that cause ad breaks to start early, skipping parts of the show you're watching. It has been a consistent and recurring issue. Don't even bother trying to use the casting option because it the issues get worse. They clearly just prioritize ad watching over their customers or smooth streaming options. Not to mention half the shows it says I can watch anywhere it only let's me if I am on home wifi.
