Preferred way to RestorePurchases

[wet jolt]

In OnInitializeStoreComplete() you can currently query for products purchased (V2 did it this way and it still works this way in V3):

private void OnInitializeStoreComplete(BillingServicesInitializeStoreResult result, Error error) {
foreach (var product in result.Products) {
bool isProductPurchased = BillingServices.IsProductPurchased(product);
...

Or, you can explicitly wait for StoreComplete to finish, then call BillingServices.RestorePurchases() and do similar to the above in OnRestorePurchasesComplete().

Which is preferred?

Also, the docs say:

"It's always good to call Restore Purchases once you are done with InitializeStore call as the user will be available with unlocked content if he/she has purchased any earlier."

But Apple says you should not do automatically restore purchases unless the user presses the button. I am assuming if I use the new bool parameter in BillingServices.RestorePurchases(/forceRefresh=/false); it won't create a popup on IOS so it is OK to always do this.

Thanks for the great question.

In v3, calling RestorePurchases on iOS with forceRefresh false will just pass the cached values(which are always maintained in sync by the os) .
But when you set forceRefresh to true, this will show up a login prompt for the user. This is the case apple stated in docs to have this call only when user explicitly wants to restore.

As we need to derive same func across platforms, we still retained RestorePurchases call and added forceRefresh param. This way, code in v2 is still compatible.
