Offline mode - Load lessons
Tomorrow I have a 24-hour trip to a Spanish country and therefore I really want to use duolingo on the way there. I was happy since Duolingo introduced the offline mode but there's no info on it anywhere.
Whenever I go into airplane mode it only allows me to do 2 lessons. When I click a greyed out lesson it says: "Connect to the internet to load lessons".
So yeah, how do I load lessons?
Thanks in advance!
