IAP not working on release

Hi all.


I have submited an app and it was releaed.

When someone dowloaded the IAP wih a code all of them work exept 1 but it worked in the test when building and also in the beta test.


It works on the ipad but doesnt on the iphone.]]has anyone else had this problem, The call for it is in the same switch and it says you have already purchased this, do yyou want to download it for free and click yes it does nothing. On the iPad it says you ave already downloaded this and it will be downloaded for free and you press ok it works fine.
