Animation previous keyframe button is not working in Unity 2019.3.3f1?

The Button previous keyframe in animation window is not working when press (Unity 2019.3.3f1). Please fix this ASAP. Thanks

Same here, hasn’t been working for a few versions now

Same here! Bound a key to it and it wasn’t working, so I was messing around with keyboard/language for 10 minutes before I realized it was the function itself not working.
