Draft box on screen question
How do I delete the Draft box at bottom of screen in email?
iPad Air 2, iPadOS 15
If you are seeing open draft mail messages, simply open the Drafts folder from your Mail App sidebar - find the draft message, then swipe to the left to expose the Delete button.
Alternatively, find the message in the Drafts folder, then touch-and-hold the draft message to expose the action menu - and tap Delete Message.
