Ipad
I am borrowing an IPad from a friend. I got her to sign out of her iCloud and I signed into the Ipad under my account. My messages are now on the Ipad, but hers is also on the messaging app. Her phone number is not connected to the Ipad I checked, it's only my number. I also deleted all of her email accounts so nothing from there either. How can I remove her messages/numbers from the Ipad? I also did a reset of all the settings and her messages are still there.
Thanks!
