I have a question for you. I'm new on Udemy and I'm not sure why this is happening. I see that your course has 3,739 students enrolled and your course is selling in about 20 euro. Why you have only earned $40? Shouldn't your earnings be 3,739x10 = 30,739 euro? (multiplying by 10 because Udemy gets 10 euro and you get 10 euro).
