Dependencies in subtasks are currently not able to be uploaded using CSV import. See screenshot of my csv file

Hi, thanks for this but i’ve done exactly this and it doesn’t work for subtasks within a task in a project. Only seems to work for tasks within a project. i.e. in my screenshot above, ‘UK ST: Haeni Kim’ is a task in a project and all the other tasks are subtasks of ‘UK Haeni Kim’.
