Problems while checking if user purchases a subscription: empty array for appLicense.AddOnLicenses, weird extra sku object for product.

[AlexMisiulia]

Hi, I'm trying to add subscriptions to my app. And I have problems while checking if the user purchases a subscription. I have 2 problems:

1. Method CheckIfUserHasSubscriptionAsync() from documentation always return empty array after I bought a subscription (I tested either with and without trial). I can see that product has property "IsInUserCollection":true when calling method GetSubscriptionProductAsync(), but appLicense.AddOnLicenses inside CheckIfUserHasSubscriptionAsync() is always empty.
2. Method GetSubscriptionProductAsync() returns strange response with 1 extra sku.

In the documentation in the code comment it is written:

// Check if the first SKU is a trial and notify the customer that a trial is available.
// If a trial is available, the Skus array will always have 2 purchasable SKUs and the
// first one is the trial. Otherwise, this array will only have one SKU.

But actually I have always 3 purchasable SKUs after purchasing a product. And weird thing is that SKU that has the property "IsInUserCollection": true doesn't have any SubscriptionInfo:

For the case when a product doesn't have a trial it has 2 skus, but with the same problem as mentioned above:
