I got the same issue than already reported: When trying to edit a task, all I got is a black screen saying "Task edit". Nothing seamingly related in the JS console. Also, I was mostly interrested to have a look at the "project timeline" but it's not obvious where to access that. Same goes for the automation part. How to access that?
