I searched on the forum for an answer, but can’t find one. In German 1 (and in Spanish 1 Spain) level 4 is missing. It jumps right from level 3 to level 5. Anybody have any ideas? 
Not German 4… Level 4 in German 1.
Level 4 does not show up on the browser version because it is a chat bot that apparently only appears on the app. At least, it appears on my iPhone and iPad.
Oh! I see that now. Thanks!
