I'm using IAP plugin in iOS device.
All my goods are consumable.
I got user's feedbacks about “This In-App Purchase has already been bought. It will be restored for free.” popped out in iOS devices.
After some search, this may be helpful. http://greensopinion.com/2017/03/22/This-In-App-Purchase-Has-Already-Been-Bought.html
Is it possible to fix this issue in SDKBOX lib only?
Or should we take care the issue by ourself? If so, please give us some steps.
