Notifications broken again

I would like to get an idea when this will be fixed. Every other update just breaks notifications again. Either they’re not at all received, random badge counts, no badge counts, badges for no new content that won’t go away, having to cycle between various all tabs to clear notifications. It momentarily somewhat worked, then broken again after update. Our business relies on the apps - computer, iPad, iPhones, so on. All entirely unreliable.
