You probably don’t remember it, but back in the days, Asana did not have the ability to do mass actions like it does today. You could only multi-select tasks and act on columns you saw. There was no box with many actions available.
However, even with this new mass-action feature, I recently found myself in a pickle: I was assigned on about 30 tasks in My Tasks, and wanted to unassign myself. Turns out the mass action box does not allow to unassign, only re-assign.
Take a second to think: is there a solution to this situation?
Yes! The trick is to create an empty project, multi-home all tasks into it, and then multi-select the tasks and click on the arrow next to the assignee. That trick does not work within My Tasks because there is no assignee field displayed. Not ideal, but way quicker than opening each task one by one.
So did you find the solution before reading?!
