Contacts
while setting up Husbands iPad my contact some how got on his iPad. I singed into his ITunes ID we had been using the same iTunes but i thought i had separated our accounts. He hasn't used iCloud so i dont know how this happened my iPhone and iPad doesn't show up in his account. I didn't connect the iPad to the computer but i had backed his iPhone to iTunes before starting to set up his iPad.
iPad Wi-Fi, iOS 11.4, New out of the box
