Hey,
I've the free plan and I created some new projects by a template. In these projects I've the possibility to get 3 hierarchy levels.
1. => EPIC
2. => Story & Task
3. => Sub-Task
I also have an old project in which it seems to be only possible to have 2 levels
1. => EPIC & Story & Task
2. => Sub-Task
How can I also get 3 levels in this project? I cannot find any settings to do this and due to it is an older project I don't want to migrate it into a new project.
