Can verify at least one thing was fixed between iOS 16.5 and 16.6.
With 16.5, I use the Notifications setting of "count", when I would tap the "2 notifications" at the bottom it would go grayed out and not open up so it would take a second tap to get the notifications to expand. So it's been a double tap since 16.5. Installed 16.6 and now they are back to opening with a single tap.
