They're still there on all the methods I have of accessing the site.
Other than what @kev74 mentioned (which is determined by how wide your screen is - if things are compressed into those pull down menus with the three dots), the only other thing that immediately comes to mind is that if you've got the Toggle BB Code ..well, toggled, then the Smilies/Emoji thing to click on would be greyed out until toggled back.
EDIT: The Toggle BB code is this thing
Side note: I'm on a new machine that doesn't have Photoshop installed yet and I had to use Windows Paint to make that. Horrible
