How can I undo timeline changes?

I’m new to Asana and loving it!! I’ve got a bunch of tasks on the timeline and I accidentally dragged or resized one (not sure which) that caused a date recalculation to a load of tasks, Is there an easy way to pull them back or do I have to work out what the original dates of the task I edited were and manually pull the others back into line?

The only way to rollback something is by clicking in the small snackbar that appears at that moment. After its gone, you are ***** :sweat_smile:
You can multi-select tasks and drag them again? Or you aren’t sure what you changed?
