Yeah I hear ya 100% on that one. It's obvious at this time that YouTube's primary goal is NOT "get this creator's video the number of views that they expect," but it has shifted very strongly to "get users to stay on the platform no matter what"
So the logic behind withholding the notification would be that they KNOW she'll open the app when they send your notif, and they try to optimize for when they assume she'd have time to click through to more videos after yours
