Detecting if a User has cancelled their subscription during the free trial period

[mzruiz]

Hola hola,

I have a user who purchase a yearly subscription and cancelled during the free trial to purchase the lifetime product. After the two week free trial period ended, the User is still subscribed.

We have logic to determine if the User has passed their subscription 'length' by checking the number of days since their last subscription purchase.

const completedPurchases = await getPurchaseHistory();

const sortedPurchases = completedPurchases
  .filter(a => ['monthly', 'yearly'].includes(a.productId))
  .sort((a, b) => a.transactionDate - b.transactionDate);

const lastSubscriptionPurchase = sortedPurchases[sortedPurchases.length - 1];

console.log('lastSubscriptionPurchase', Object.keys(lastSubscriptionPurchase));

How can I use the above info about the purchase to determine if a trial has ended and the subscription has been cancelled? Is this something with the App Store server URLs?
