The web version of Lingvist keeps showing "You've completed the Spanish memories section". This also happened to my girlfriend who is learning English (different acc) "Du hast Englisch von Lernen Sektion"(which is grammatically wrong German btw..). However, when I use the App on iOS I still keep getting "new words". So this is definitely not true and some kind of bug. I am also still at 2700 words. We use Windows and Mac with Firefox and Safari. I am a daily learner of Spanish.
Web Version tries to keep us out ;-)
