"Lost emails: I updated my IPhone 12 Pro Max and now my emails are disappearing. When I open my emails and read them sometimes I just leave them in my inbox so I can refer back to them. But since the update they are disappearing after about 24 hours. Help!!! I am missing some very important emails."

New App Password:
You’re using a new iOS version. So, a new app password is likely what is needed here. So, try creating a new App Password. Something typical for modifications. You would log in using that password, rather than your eMail password.
