[Android] IAP Subscription 'developerPayload' is missing

Unity 2020.1.2f1

IAP 2.2.1

Buying a subscription works, when I reinstall the application, restore also works, But when I just log out and log in to the app I get a product subscription with receipt which not contain enough information, the ‘developerPayload’ field is missing. How I can check subscription status?

‘This product is not available for SubscriptionManager class, only products that are purchase by 1.19+ SDK can use this class.’ - What SDK is meant?

#if SUBSCRIPTION_MANAGER
                    if (item.receipt != null)
                    {
                        if (item.definition.type == ProductType.Subscription)
                        {
                            if (checkIfProductIsAvailableForSubscriptionManager(item.receipt))
                            {
                                string intro_json = (introductory_info_dict == null || !introductory_info_dict.ContainsKey(item.definition.storeSpecificId)) ? null : introductory_info_dict[item.definition.storeSpecificId];
                                SubscriptionManager p = new SubscriptionManager(item, intro_json);
                                SubscriptionInfo info = p.getSubscriptionInfo();

                                Debug.Log(string.Join("

",
new
{
"Information about subscription product: {item.definition.id}", “Purchase date: {info.getPurchaseDate()}”,
"Expire date: {info.getExpireDate()}", “Is subscribed? {info.isSubscribed().ToString()}”,
"Is expired? {info.isExpired().ToString()}", “Is cancelled? {info.isCancelled()}”,
"Is in free trial period? {info.isFreeTrial()}", “Is auto renewing: {info.isAutoRenewing()}”,
"Subscription remaining valid time until next billing date is: {info.getRemainingTime()}", “Is this product in introductory price period? {info.isIntroductoryPricePeriod()}”,
"The product introductory localized price is: {info.getIntroductoryPrice()}", “The product introductory price period is: : {info.getIntroductoryPricePeriod()}”,
$“The number of product introductory price period cycles is:: {info.getIntroductoryPricePeriodCycles()}”,
}));
