Just reviewed the app saying that I've already told literally everyone I know who uses the app to do what Google suggests for the shoddy notifications (which if you look seems to be in almost every recent review), and I get developer feedback telling me to do what's on the link I already used to try and fix everyone's problems. So, yeah, you lost the second star, Google. You have an issue with your flagship chat app and notifications. Fix it. Don't force us to user an app with known issues.
