The new Undo/Redo functionality that was introduced as part of the auto save feature is not robust enough. The tool needs a true field by field undo/redo.
Currently, if you want to undo field changes one field at a time, you have to highlight the task, update the field, "step off" of the task, highlight the task again, then update another field. Only then will the Undo button result in a field by field undo.
If you don't "step off" of a task when making multiple field updates to it, then using "Undo" results in all of the field changes disappearing at once.
