There seems to be no way to actually mark a task as complete, so I had to delete the tasks I actually did complete and therefore have not gotten in-game rewards. There is also no way at all to contact support. If you join the Habitat Help Guild that is supposed to allow you to ask questions, there is no obvious way to post a question there. There is a button to leave the guild but not one to post a question. This app is terrible and is a waste of time.
