I applied for a personal developer account. After registering iOS devices at https://developer.apple.com/account/resources/devices/list, the status of each device shows Ineligible for 14 days. As a result, my project cannot be debugged with this account, and my app cannot be published in the App Store What should I do in this situation?

I have a problem like the title here, but it only occurs in some mobile phones and some networks. It seems that it has little to do with the code level. How to solve it. When it is clear, some iOS 15 will appear, and iOS 13 does not have this problem.

I use StoreKit test in Xcode to test Consumable Project. I want to test the refund of Consumable Project. When I open the Manage StoreKit Transactions of Xcode 13, when I select Non-Consumable Project, I click the Refund Purchases button to purchase There is no refund for items, but when I click on the Consumable Project, I cannot refund. I test the refund function of Consumable Project. We know that the relevant document is 'https://developer.apple.com/documentation/appstoreservernotifications/responsebody', but we don’t know how to trigger a refund in a sandbox environment
