I have a problem with a restorable item. I can buy the item with success but I can't restore i t- a method restorationCompleted returns -37. My application has 4 iap items one of them should be restorable. (demo and full version)
1) what method should I call on start (getProductData(ids..) or getRestorableProducts(..)?
2) Can I test the restoring behavior on a simulator? I tried the game "Battletank" from samples but restorationCompleted returns -37 also.
3) regarding drm as I know a restoring item is available if the application has drm model. What should I do to set drm for items?
