Emails I send to myself do not reach my In box
I have a recurring problem that emails I prepare or attempt to forward to my icloud mail box on my iPad go to the "Sent" box, but they do not go directly to the "In" box. I then have to manually move the messages to the In box. How can I can I get the sent messages to go directly to the In box, as well as the Sent box? Thanks.
iPad, iOS 12
