ToDoList - Task manager

I love the simplicity of this app and love that it’s open source. My only complaint is that every time I launch the app after force closing, it gives a pop up that says “you are not logged in to iCloud. Your tasks won’t be synced!” I’ve checked all the settings I can think of and can’t figure out how to stop it from popping up. It’s very annoying. Devs, please help me find a resolution to this.
