collation: utf8mb4_unicode_ci  is changed now but we have a new problem with emoji's. The add emoji box is active in the menu but doesn't show up on the post form (context) and post to feed box. Also when we use postform (context) we can't see privacy/visibility. When we post a message we get an error and then box pops-up so we can change privacy/visibility.

edit: smiley button is  visible on desktop, on mobile it pops-up and disappears after 1 second (even faster)

edit 2: you can use your keyboard emoticons😑 , disabled the visibility on phone.

Smiley problem solved
