This is very frustrating. The “Preserve Local Transform” option is missing from the new importer. Our character animation jitter at the feet without it. I tried importing with 4.27 and 5.1 and the animation looks correct with Preserve Local Transform. Disabling the Interchange plugins in 5.5 will fallback to the old importer with the Preserve option showing, but it also disables Mesh Painting which we use… Why is there such a dependency? Please fix this.
