I am trying to figure out how to have newly added data populate a CollectionView (top) or ListView (bottom) instantly instead of this default fade in that takes up to 1 second to show the new data. I'm doing this in Windows.
Is this an animation that can be overriden? If it's not an animation, what is it? I simply don't want to wait for this animation to see the newly added data and want it canceled or just quick such as 10ms. You'll see from this gif that as soon as the data is added, the top line will show the new data with the line number. Then you'll see the CollectionView and ListView show the data about 1 second later.

What is the expected behavior and how does that differ from the actual behavior?
Do you use other themes or third-party plugins?
I create a new MAUI project and add items in ListView and CollectionView in windows 11, when I add items to the Listview or CollectionView, no these appearing animation.

2023-06-01T05:20:00.69+00:00 Could you share your tested device version? I cloned your demo and test in the window 11 OS build 22621.1702, no these appearing animation as well.
For your scenario, it is recommended to open a support ticket for this. Please contact our paid phone support at MS Support. You will get 1:1 support on that.
