The bug is with the default animation editor swapping the cubic ease in with cubic ease out upon export, and vice versa. Plugins like Moon and any others that let you use/create animations did not seem to reproduce the bug from my (very limited) experience I had with them. Alternatively, you could use the default animation editor as is and then replace all your ins with outs and vice versa before exporting, but that would be tedious.
It’s been a while since I’ve used the default animation editor, so there’s even a chance that it’s been fixed and I’ve not noticed
