I'm running iOS 13.4.1 on an iPad Air 2. When I click on an email form field in Safari, the keyboard suggests two email addresses, one labeled "home" and one labeled "email". The "home" address is the address I use for my Apple ID, but the "email" address is an old email address that I haven't used in over ten years. How did iOS find this email address, and how can I get rid of it?
The old email address still forwards to my main email address, so it's possible that iOS extracted it from my mail, but I have other email addresses that forward to my main address that it doesn't suggest. I couldn't find anything in my iCloud account that's linked to the old address, and I didn't own any Apple products ten years ago. Any ideas?
