[solved] How to view completed subtask

I would like to know if it should be possible to view a completed subtask in the task list view ?
Currently, when I mark a task as completed I have a new Completed option in the menu and I am able to work on it.
But when I mark a subtask as completed, the subtask disappears of the task list and I am not able to find it anywhere :frowning:

I run nextcloud 19.0.2
I use web interface with firefox 80.0 under windows 10

Thanks in advance for your help.

SOLVED : it is possible in the category-list view. A button appears “View All Completed Tasks” at the bottom of the page
