I didn't really test it in 3.0 and 3.1, but when I upgraded to Vanilla 3.2, none of the buttons above the text box in Advanced Editor were responding. Disabling Show All Emojis fixed it, but now I get only 8 emojis 😪.
If you change from Advanced editor to Rich editor, you get a load of emojis with it.
Right you are Kaspar!
Both Advanced & Rich Editors were on and I had tried shutting off Advanced but then just got a plain text box, so I turned it back on.
This time I turned Advanced off and got the plain text box again, so I turned Rich off and back on and that did the trick.
