Thankfully I've got screenshots of 'em. Took them as I got them.
That said, uuuuuhhhh... When looking from the messages screens, or from the big pic gallery, it shows the small square tab with the new updated images -- however, when I actually press the images and enter them fullscreen, they're the same old images as they have been.
Anybody else experiencing this issue? I'm on Android mobile app, if it may matter due to platform.
