Attach photos to email

Apple Support provides a "how to" article for iOS 27:

Add email attachments in Mail on iPhone - Apple Support

Eg: says:

"Attach a photo, video, or document to an email

You can attach and send documents, videos, and photos in your email messages for recipients to easily download and save.

1. Go to the Mail app  on your iPhone.
2. Tap in the message where you want to insert the attachment, then tap  above the keyboard.
3. Do one of the following:

• Attach a document: Tap Attach File, then locate the document in Files.
  • In Files, tap Recent , Shared , or Browse , then tap a file, location, or folder to open it.
  • Attach a saved photo or video: Tap Photo Library, then choose a photo or video. Tap  to return to the message.
  • Take a new photo or video and attach it to the message: Tap Take Photo or Video, then take a new photo or video. Tap Use Photo or Use Video to insert it into your message, or tap Retake if you want to reshoot it.

Note: If your file exceeds the maximum size allowed by your email account, follow the onscreen instructions to send it using Mail Drop. See the Apple Support article Mail Drop limits."

If the above method is not working for you:

You might want to send feedback to Apple. If others have a similar issue and Apple receives enough feedback, we may see the situation addressed in an update:

Apple's feedback website: Product Feedback - Apple

If you haven't already tried it:

Restarting a device will often restore order when something is not working as expected. (deletes temporary files, re-establishes connections, may update recent setting changes and more).

Wondering whether the iPhone is still completing the upload changes that occur behind-the-scenes (eg: re-indexing etc.) after this major upgrade. This uses the iPhone's energy and resources intensively, and can take quite a while.

Leaving iPhone plugged in overnight a few times may allow the process to fully complete, if it hasn't done so.

Else: If it is a "bug" then, as Apple users, like yourself, nothing we can say or do can help much.

Although it won't help immediately: If Apple receives multiple feedback reports on an issue, then it is likely to be addressed in an update. All feedback is carefully read and logged.

I did all that. Not a new user. The result is a picture frame (a space with a small square with a ? in it), no picture. I get the same result on my iPad but not on my Mac.
