Confirm passcode asks for passcode of old, sold iPhone
Hi, I’ve been getting the prompt to confirm my passcode since I changed my it. I tried to; I put in my Apple ID password, then it asked for my phone passcode which I put, then it asked for the passcode for my first iPhone 7. I have removed the said iPhone 7 from my trusted devices in settings and on find my iPhone. I have even changed my Apple ID passcode so if some how I was still logged in, it’ll log out. I have restarted my phone multiple times, but every-time I get to that point, it still requests for the passcode of that iPhone after I put in the passcode for my current iPhone. I’m really frustrated and need help. Also, I saw a reply someone had years ago to turn off two factor verification but I checked and I don’t have it on.
iPhone 12, iOS 15
