Google is actually uniquely bad at this. The system that displays notify banners for Cloud is a too-many-cooks-in-the-kitchen mechanism that requires multiple layers of authorizations, signoff, scrutiny, and binary changes to their UI. For that reason, it isn't (at least, didn't used to be) blocking to roll a feature out for that pipeline to work, so a lot of things that should be top-banner messages weren't.
