Yesterday the status of my app became "Pending Developer Release". I look into promo codes and it says " They are for non-commercial use and will expire four weeks after they are requested."
1)What does it mean by "non-commercial use"?
2)Do I have to request all 100 codes at the same time or can I request a little at a time?
3) Is it one code per download? I mean, can only 1 person use this code, I can't give this same code to several people?
4)How will I know whether someone used the code or not?
