Different Apple ID Purchase in my iCloud Backup
I have just received a message stating "This iCloud backup includes purchases from the iTunes Store that were made with a different Apple ID" then giving another ID address. How can I check what purchases were made from this other user in my backup as I'm unaware of any. Will they show in my purchase history if I didn't make them? I've had a look and there's no purchases in my account showing under this ID (although I do know it). They must show who did what somewhere so I can check what this person has put in my cloud.
