Hi all, this solution worked for me:
- Hit the “…” at the top right of your project window to access more actions.
- Select “Search this project”.
- For the “In any of these projects” field, add the project from which the task was deleted.
- Select “Add filter” at the bottom of the Search window.
- Hover over “More” and select the bottom option, “Deleted”.
- Conduct the search.
- Rejoice as your deleted tasks appear
I don’t know if there is a 30-day limit before deleted tasks are permanently deleted, but these steps worked for me.
