Old iPad doesn't show on Find my Device
I had a super old ipad mini and was just contacted by someone who found it and its still signed in to my apple ID. I did the "remove from my account" but didn't erase it first. It doesn't show up on my Icloud but it shows on the old iPad that it is still connected to my apple ID. I don't care if he keeps it but I do want to erase it and for him to log in with his apple ID it needs to be off mine. How do I erase it or at least get it off my apple ID?
