I am running a forum with version 1.0.9. I just got a report that Apple devices running iOS 10 don't see the smileys or post editing icons. It appears this problem is fixed on version 1.1 beta 3 that is running here. BTW, this happens on Safari or Chrome.
It is reported as bug at http://www.elkarte.net/community/index.php?topic=4006.0
But the fact that here works is interesting.
Let's move the discussion there, please.
