I found a slight glitch with the Course on Mobile......
So if you go to your Duolingo app, you may see that this language is "unsupported for mobile". After a few times opening and closing the app, it started....working! I was then in a lesson, running fine when all of the sudden, the message pops up! I do not know why this happens when it obviously worked for me. Anyone have a reason? Thanks!
Nevermind, there are some glitches such as not teaching you the words before prompting you with sentences.
RE-EDIT: I did an entire lesson on the mobile app with only a bit of trouble near the beginning.
