When adding a step in Next steps, if you click off the step and onto a list item, the step is NOT saved. It only saves the step if you press Enter to add another step. This is different behavior to adding text in Notes section. Text added in Notes section is automatically saved when clicking onto another item, as are other fields.
Please make the behavior the same, when you are entering a step, automatically save it when clicking off, going to Notes in the same task or into another To Do list entry.
