iTune Connect Financial Report Result Not Matched?

[marceloc]

Hi all,

I am very new to iPhone development and I just launch my first iPhone app in appstore. Recently, I have received all of the financial reports from different countries for the first month of sales from Apple. The result is very disappointing. From the reports, there were only X downloads in total. However, according to my data log (which I keep track of all downloads on my side), there were more than 10X downloads worldwide for my app for first month, and among all these downloads, all my users are active users because they will need to go through the registration process and confirm. Therefore, the 2 results have huge discrepancy (almost 10 times difference). How can that be? I am very concern. Is there anyone who has the same experience?

It should not be I am alone! Thank you.
