Several members have reported not having sales data for their iOS and Mac apps for 12/16. We took a closer look and found that for some developers, daily reports for the 16th are simply not available for download within iTunes Connect. The preview is there but the complete report isn’t.
This is the first time we’re seeing this type of issue. In the past, when iTunes Connect had similar issues they were corrected in a matter of days.
If auto import is turned on for your account, when/if those reports do become available they will be imported into your account automatically.
