In the end, I do the same with taking the 1099-K total and then expense the difference. It is annoying it has to be a such a black box. Why can't the monthly report that comes with the payout also include that extra total amount. So then you have a ***** amount minus fees and then equals your check/paid amount. If they can figure out the paid amount, they must have the higher amount as well that winds up in the 1099-K. This method winds up leaving out whatever international amounts when you don't earn enough for the 1099. So you get paid the money but have no documentation on the true fees.

I got this too yesterday after submitting a different app update the day before. Closed out Xcode completely, went back in, cleaned build folder and uploaded again. Worked. It seemed to be mixing up the two different signatures.
