In app purchases are being restored automatically on iOS in Sandbox mode

It looks like the application tries to restore purchases automatically on iOS. These messages were logged just after initializing Purchasing:

After these messages all non-consumables were automatically restored.
Unity version is 2019.2.12f1, UnityIAP version is 1.23.1.

Did anyone encounter a similar issue? Any help would be kindly appreciated.

 

So you are receiving the ProcessPurchase call back for these products?

 

I do not think so, because there is this line for every product that is being purchased:
"Debug.Log(string.Format("ProcessPurchase: PASS. Product: '{0}'", args.purchasedProduct.definition.id));" and we did not encounter similar messages while checking logs.

 

If ProcessPurchase is not called, then restore is not occurring and users would not be awarded the products.
