Duolingo App Heart Refill
Just for security I bought a heart refill a few days ago but when I go into a lesson there is no option to use it! If I go back to the store to see I maybe I had tapped wrong it said they were enabled. Now when I go back again it looks like I never bought anything at all. What's going on? Thanks! D
Do you mean hearts refill?
This is only available from the apps because they are the only place that you can still see the 3 hearts system in use. You can buy one in the app but you must use it in the app. If you then go to the web interface it refunds you the lingots because you cannot use them on the new strength interface.
