When you receive an invoice from Apple App Store, please note that:
- the date that is listed as the date of the purchase is actually the date on which the invoice was sent.
This means the invoice could relate to a purchase made quite a few days prior to date displayed.
- when the invoice shows multiple purchases with the same date, it is often due to different purchases grouped into one invoice.
This means that the purchases listed could have been made on different days, sometimes even on a different week.
To have an accurate overview of the purchases you have made via iOS, the best thing to do is to verify your purchase history, instructions on how to do so can be found here: https://support.apple.com/en-euro/HT204088
