web interface and app for Windows
what's wrong with both? The window with "Add your project here" with the HUGE red arrow is closing EVERYTHING (the list with tasks - both in the web and in the windows application! How to put this away or redeem moneyback, as this is not workable absolutely!
In order to start adding tasks in Todoist, you have to add them to a certain project. When you add your first project, this arrow will never be shown again.
If it still is, please send a screenshot showing this issue to firstname.lastname@example.org
