Today I misplaced my iPhone and when I logged into iCloud to see if I could find it. I found out my old iPhone 5 was still listed that I had traded-in back in 2015 to Best Buy. It says "Offline" under "Find my iPhone", I have the option to "Erase" or "Remove". I'm pretty certain I did a factory reset when trading it in. I checked under "Settings" > "My Devices" in iCloud and it only shows my current iPhone 8 Plus signed-in/Active. Is this a glitch or should I be concerned? What do I need to do to fix this?
Thanks
