No, that's not what I'm trying to say. it took me a month to get a response. I'm saying that you usually get your response 2-3 days after the biometrics letter but in some cases where you apply online, they send the biometrics letter to you early to let you know that we have received it.
In conclusion, my whole point is that the biometrics letter takes time to be emailed so you have nothing to worry about at all, you barely made it a week since your application whereas it took me a month, so do not worry there's nothing wrong.
Best of luck!
