Hello, I'm trying to use IAP transactions and display them in a store, for convenience. I've set everything according to the tutorial, after initialization I've got a message "UnityIAP: Promo interface is available for 4 items", but in the store, all the IAP items are disabled - purchase buttons are not interactable, and even if I make them interactable manually and then click - nothing is happening. I'm using store view and transaction item prefabs, which worked just fine for me with virtual transactions. What am I doing wrong?) I've attached some screenshots of my setup: Thank you in advance!!
