Unity IAP subscription error resolution
First of all, I recommend that you no longer use the checkIfProductIsAvailableForSubscriptionManager detection method in the IAP Demo.
The second is the related processing source code of subscription

Usage
Called after payment initialization is successful
and updates after purchasing a subscription
Subscription processing
The subscriptionDict dictionary returns the purchased subscription product name and subscription status dictionary.
True: Subscription | Auto-renewal on
False: Cancel subscription&& Close subscription&& Subscription expires
