Hello Apple Developer Support, I hope this post finds you well. I have several questions regarding the refund process, developer commission, and revenue payout, and I would appreciate your insights on the following: 1/ Refund Process: When a customer cancels an order, when will Apple process the refund for the developer? How long does it typically take for developers to receive the refunded amount? 2/Developer Commission: How does the commission for developers work in the event of a refund? Does Apple adjust the commission or deduct any percentage in case of a refund? 3/Refund Notifications: Is there a notification system that alerts developers when a customer cancels an order and a refund is processed? 4/Revenue Payout: How long does it take developers to receive the revenue from purchases, and is there a specific payout schedule for this? 5/Commission Percentage for Small Earnings: If the developer's total earnings are under 1 million VND, what is the commission rate that applies? Thank you in advance for your assistance. I look forward to your response.
