I am in the process of implementing a in-app purchase that is based on time. This purchase will activate premium features of the app for 30 days. After the end of the 30-day period it will be consumed. How can I find the purchase date from within the app or from the InApp server?
The Purchases map of the manager_OwnedProducts does not provide the purchase date. There must be some way of obtaining the date of the initial purchase. My initial implementation was to save the purchase date locally on the device at the time of purchase but that won't work if the use uninstalls the app and later re-installs it during the valid time period.
