How do I make tasks on a project disapear after I mark them as complete? I used to be able to do this… Thank you!

Due to the new multi-filter options your saved view might got changed.
This is where you can change the filter you want
And then save it as default view by clicking on the „…“ in the top menu (top right) and then click „Save layout as default“
Please note that if anybody else with access to the project changes the default view it will change it for you too.
