Up front, I'm working this closely with Apple right now and we're working to try to sort out the issue. Problem is the tablet is in a remote physical location and I don't have access to troubleshoot. I'm going to try to recreate this issue with my personal tablet. I'm posting here for awareness and help to try to figure out what I did (or is this a security flaw). Months back, I upgraded to an iPad Pro 10 inch. I followed the exact steps for preparing an iPad for sale (removed Find my iPhone, erased everything) and a few months later I decided to give that tablet to my child. I created an Apple ID under family sharing and set up the iPad with that Apple ID. Looking at my e-mail records, I see the e-mail notification from my child's family ID when I logged in to the device. From that point forward, it was the only ID signed on to that device according to my memory and my e-mail records. Fast forward to now, where I was notified and received proof that my Safari saved passwords showed up on my child's device. My only family sharing setting turned on was App Purchases. I never logged into that device with my ID (that I can prove at this point with my memory and e-mail records). On the surface, it seems to me that the device (and that AppleID) some how picked up old data from my tablet (sounds impossible) or sucked in my data (possible?). My child does not have iCloud set up on that account, I just tried logging into that account on iCloud and it asked me to set up iCloud. Is it possible my child's account pulled from my iCloud information instead?
