My live photographs taken are not showing up on the recipients text message as live. It goes through as a still photo instead.

Ask the recipient to follow this

How to share your Live Photos

1. Open the photo that you want to share, then tap the Share button .
2. If you want to share the still photo and not the Live Photo, tap Live in the upper-left corner of the photo.
3. Choose how you want to share your photo. Note that if you share via Mail, the Live Photo is sent as a still image.

When you receive a Live Photo on your iPhone or iPad via Messages, tap the photo to open it, then firmly press and hold to see it come to life.

If you're using Messages on your Mac, double-click the Live Photo to open it. The Live Photo plays through once. To play it again, click the LIVE button in the bottom-left corner of the photo.

This has started happening to me too. I'm on iOS17.2.1 and other users on this are not having the issue. I've checked all the settings and I just can't figure why...
