I'm testing auto-renewable subscription and I have the following problem:
- I make a purchase on device A
- With the same AppleID I restore the receipt on device B
- I change AppleID (from device settings) on device B
- I still have the receipt on device B that makes me a paying user
In this way a purchase can be duplicated just logging-in one time with a paying AppleID. So, how can I delete a receipt from a device? Or tell me if there's another solution...
