I don't see any Heart Refill option in my profile. Is it discontinued? If it is not, how to get it?
well the worst change will be when they get rid of immersion, but I do agree with the rest of your comment.
Hi there, I too want to try it but I am hearing some bad reviews about it. So that's okay.
Why? I mean, I haven't used it ever before. How it worked when it was available?
For all lessons. Kinda like a test, except the hearts were everywhere. Even on lessons.
The "hearts" scoring system isn't completely gone. If you are using Windows 10 on your PC or laptop, you can install the Duolingo app from the Windows store, which still uses the "hearts" scoring system (no refills, though, just extra XP for completing the exercises without errors)
