I'm running ArcGIS Pro 3.4.4 and this is still an issue. We work with LiDAR a lot and not every software that processes LiDAR writes in horizontal or vertical projection info. Which means when we add LiDAR to a project or open a project with LiDAR files in it, we get bombarded by a series of notifications that we can't turn off and have to try to close out of to access things like the catalog pane. It's even worse because of the slide graphic applied to the notifications so you have to strategically try to close them while they move around.
