According to Revenue Cat, I made $151 with 24 transactions in June 2024. However, Apple only sent me a payment of $92.46 today stating 19 units sold.

The previous month, Revenue Cat reported $44 in revenue and Apple paid me $37.29, so I know up until this month, Apple was paying me in full minus the 15% fee for small businesses.
How can I figure out why Apple paid me less than usual. I have started receiving international payments, so my hypothesis is that Apple is not paying me for countries outside the US and Canada. If so, how do I start receiving those payments as well?
