How to understand the data return from iTunesConnect?
There's an app with subscriptions (week, month, and year). The statistics for yesterday slipped a strange return
In Subscription -> Summary, I see that refund was 1
In Sales -> Units, I see the number "-8" on schedule and -4 in the table when filtering on site
The refund was for the US, but purchases in the United States especially was not, and it is strange that these 8 returns were held in 1 hour time judging by the statistics in 24 hours. The money also shows how the return for 8 units. Plus I returns I have never had before.
I don't understand what it means. Some mistake the AppStore or that I do not understand.
