I gave my old iPad to an ex, and before doing so, I deleted all content and reset. I think she may be seeing my iMessages and e-mails. Is this possible?
I used to use the Wi-Fi in her apartment for both new iPad, my iPhone, and old iPad she now has. If I use Find my iPhone to list devices from my iPhone, all 3 devices show up, but the old iPad shows offline. Is there a way of checking what devices have access without asking her obviously?
