Ciao 👋 you know how, every now and then, I'll send you an email about a new Duolingo feature? and then you login to Duolingo and -- grrrrrrr 😤 -- the new feature isn't there? well, don't worry -- it happens to me too! 🙈 I'm always seeing and hearing about these cool new features that still haven't landed on any of my devices it can be so annoying a lot of this is down to Duolingo's classic A/B testing -- something they've always done to figure out which features people like... and which ones...
