I used my Huawei developer account to sign in to AppGallery Connect, in which I have two game apps – app A, which was released in Singapore and app B, which was released in Thailand. On the product management page, the default currency of in-app product prices in app A is USD. However, when I selected THB as the currency for in-app product prices for app B, the currency for app A also changed to THB. I want to know what is the currency determined by?
