So I'm testing out an in-app purchase in my app. I've got the code set up properly and everything, but when I do attempt to buy or restore in the sandbox environment, I get this error:
MZCommerceInAppBuy.App BuyInfoDataAccessFailure_message [Environment: Sandbox]
I've never seen this before, and I am finding only one Google search result from someone else who has. It never was solved. Has anybody seen this?
I figured out a solution. The problem was coming because I was adding an in-app purchase to the current live version of my app. I created a new version of my app and changed it on my target to the update version.
I also downloaded a new development provisioning profile. I'm not sure if this is necessary, but I wanted to add that I created a new one just in case.
When you add in-app purchases to an app, you must create a new app version even for testing.
Note:
Just a side note. I noticed while I received this error I also wan't receiving any in-app purchase products. You will not receive any products until you create the new version.
