Mail push notifications

I’m a long-time Apple ambassador and use Apple devices in my personal and business life. For 11 years I asked your engineers to fix the problem with push notifications in mail app. They partly did it (after email to Craig Federighi) - but when I’m offline for hour or more, I don’t receive them. At the same time if there’s a new mail which was sent less than hour during this period it will push more old notification. I’ve checked it in the following versions: iOS 16.5, 16.6 Beta 2, 17.0 Beta 1; iPadOS 16.5, 16.6 Beta 2, 17.0 Beta 1. Seems that the problem is close to being solved, but not for 100% yet. Who has the same issue?
