Unity In-App-Purchases 5.0.3 will invoke OnProductsFetchFailed callback when fetch product success on the iOS platform. I added some logs on the StoreKitManager.swift file at the fetchProducts method, it shows productUseCase returns the successfully fetched products, and invokes the callback method…

Hi @chenxi141017_unity , you are correct. This is known issue and a fix is already underway. It should be in the soon to be released In-App-Purchases 5.0.4, which will have a notification post in the In-App-Purchases topic section.

Hi @chenxi141017_unity,

The Unity IAP packages 5.1.0 and 4.14.0 are now available. 5.1.0 (rather than 5.0.4) should contain the fix for this issue. Please try updating and let me know if it solves it.
