Apple financial reports discrepancies

Have any other devs have experienced this problem…

My game has been on sale a couple of months and I have now had two financial reports from Apple.

Both of the financial reports give very different total sales figures to the daily/weekly Sales and Trends shown in iTunes Connect.

The difference is more than 50% less total sales than shown in Sales and Trends.

Does anyone know why such a difference could occur? Apple have replied stating:

I can understand say a 5-10% difference due to this but how do we get to 50% less total sales in two monthly reports?

If this isn’t cleared up I won’t be able to continue developing apps for iOS.

Any advice?

Did you used your promo codes? When promo code is used it’s shown in “Sales and Trends” as Paid app. I had one day 18 paid apps being shown so i thought for 10 seconds that i’m rich but then i realised that i gave 18 promo codes to ppl day before. Maybe that’s your difference?

Another thing that from what I recall plays in is if someone “buys” an app he already owns on the account its still processed as “click to purchased” while the user will naturally will get it for free
