I'm having this issue too but on my iPhone. Prior to the update to iOS 14, I could email myself and others multiple images as attachments. After the update, images are no longer received as attachments but rather embedded in the body of the email. This is very annoying as I use this heavily for my work, constantly taking images of product, pallets, damaged cartons and emailing to myself or others. Although someone on here is stating that it shouldn't have changed...clearly it did and it's not on the email client side since the only variable that changed was the iOS update. Nothing else changed, email client or otherwise.
