Hi, I've had this issue since last year and it is really beginning to bother me as I cannot find out what has gone wrong. I have already searched multiple times on Google and around this forum but I can not find any clear solutions to this issue. I have created an IAP Button to remove adverts from the game. It does not seem to work at all and always gives me the error of: "Purchase failed because Purchasing was not initialized correctly" followed by a message of: "IAPButton.OnPurchaseFailed(Product , PurchaseFailureReason PurchasingUnavailable)". I know this has probably been asked before but I have tried the sample projects from the past and they are too outdated to work. What causes this issue and how can I fix it? Attached is a screenshot of the component for my button, in case it is needed.
