Traded my iphone in on Sunday, started the erase process in store and employee took it to the back. I got home and saw it was still on the find my iPhone app and iCloud, removed it from there and says device will be removed in 30 days which I'm assuming is because I have the theft and loss coverage. When I go to settings , Apple ID, it's still listed as one of my devices, when I click on it it shows me find my iPhone on, with the model, iOS, serial number and ime. It gives me the option to remove from account. Is this typically normal? Can't remember if I ever had it still displayed after a trade in. I'm wondering if it was properly erased before I left the store?
