iOS 10.1 public beta 3 smileys

[cj1900]

Hi, after updating to the iOS 10.1 public beta 3 I've noticed that the animated smileys contained within imessage have disappeared. A search of the app store shows them as installed however the word installed is greyed out. As such they can't be removed and re-added. I am using an iPhone 6s plus and in beta 2, the smileys were working as expected . Weirdly , 3 of the smileys show in the recent tab and I can use them but the rest have gone ! Has anyone else experienced this ? Thanks in advance!
