Sharon has an iPhone XR with a mess of reminders in it, along with notes. But when she updated the phone, her lists all disappeared. Leo says that there are a whole bunch of lists in reminders. So Sharon may have overlooked them. If they are missing, they might be on iCloud. How can she find them? She has no idea. Leo says to go to iCloud.com and log in with your Apple ID. You can find that info in your phone settings. Once you log in, you can snoop around until you find it. It may be in notes.

So if you had more than one email account, the notes may be synced there. Also check out the notes section in Gmail.
