应用内购买无法为某些客户工作或恢复

Question

我从我的一些客户那里收到的是，即使他们在应用程序购买中，也没有加载产品。但我的大多数客户都没有这个问题。我指示他们做恢复操作，但这没有帮助。问题是他们可以在具有相同Apple ID的其他设备中正确恢复。

没有特定的设备或IOS版本，应用程序没有崩溃。只是它说正确恢复或正确购买，但它没有这样做。

这让我很疯狂，因为我在许多设备上试过，它对我来说是正常的。

我想分享我使用的代码，这可能有助于您理解我无法解决的问题。

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {

    SKProduct *validProduct = nil;
    NSUInteger count = [response.products count];

    if( count > 0 ) {
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products Available!");
        [self purchase:validProduct];
    }
    else if(!validProduct){
        NSLog(@"No products available");
        [self hideProgressHud];
        isProgress = NO;

        UIAlertController *alert = [UIAlertController alertControllerWithTitle:LocalizedString(@"Notice") message:LocalizedString(@"Product is not available now.") preferredStyle:UIAlertControllerStyleAlert];
