Nah, they added seriously annoying characters that cannot even be disabled in settings.

They are so anoying, that when I tried looking them up on forum (after mere 10 min of returning to duo lingo), I got the solution in the very first post. Everyone was complayning that they cannot focus or are outright enraged by these characters and that the best known solution is a custom filter to adblock... (making the service unmonetizable.... obviously)
