Same, still can’t remove Memoji. I started this whole rabbit hole of web searching this morning because I was searching for a way to create my own self-selected Favorite Emoji tab, which there is not (because it might clutter the experience to have a “favorites” AND “most frequent” section on my emoji keyboard).
The categories that clutter my keyboard are the Stickers & Memoji’s (even though I have NEVER used stickers or Memoji’s in the 10+ years I have had iPhones). I would prefer self-selected favorite emojis over stickers/Memoji’s cluttering my keyboard ANY day.
Poor user experience Apple, let us turn off Stickers AND Memoji’s! And yes, I already went to my Keyboard settings and toggled off Stickers, AND yes, I already deleted any human Memoji’s, but you don’t allow users to delete the prefilled Memoji’s like the dragons or crabs or sheep’s, and yes, I restarted my messages app (and even my phone for good measure so please don’t give the advice to delete Memoji’s straight from the Messages keyboard either).
