I have read many of the forum posts about this topic, many dating back to 2017. I would like to bring this back up again. Not being able to correct completed dates for tasks hinders accurate tracking of tasks. Our industry is not always on Asana daily and often do not update tasks until specific meetings to ensure accuracy of the project. Not having this feature has use wondering if Asana is the appropriate solution as we do not have the features for accurate project tracking.
