First plane training mission "Z" key wont's zoom out in AG attack

Newbie here. In the the first airplane training I get all the way to the ground attack part, it says hit “Z” to zoom IN and it works. It then says hit “Z” again to zoom out - and nothing happens. I can still Escape key to get out of the mission, so it’s not frozen/locked up. I did this 6 times, same results, new logins, etc. I also tried w/the General key binding (not the Airplane zoom) and same results…
So I can’t get past the first plane tutorial. My hardware is 5600x, 32GB, 3070 at a smooth 60fps. Thx!
