A/B testing russian??
Second post ever!!
The app always notifies me that Russian is not available yet. This morning I actually did Russian on the app :D. The step is to select Russian on the site and then go to the app. You'll get a popup saying not available for mobile. Click your backspace button and then press strengthen (edit: the third time I tried it I didn't need to press strengthen because it went straight to Russian).. This is the only step I've tried to get it on the app. Good luck ;). Proof. https://drive.google.com/file/d/0BzFZ7XZ-mS5dbndVVVBjWVk2REk/view?usp=docslist_api

The app stopped letting me progress further. Strengthening still works though... I had to use the site again to progress on to the newer section because the app is not letting me. Better than nothing.
The mobile site is slower and the voice doesn't play automatically all the time. I have to tap the button to play the voice multiple times for it play.
Word suggestions doesn't work (also can't tap and correct automatically) and more mistakes on the voice dictation. The app offers a more compact design and the voice is much clearer. The notes are great, but like manuals for everything I never read them.
I suggest you do read them, the team did really great job in creating them (not me, so I'm not bragging, those are just really great materials). They are not just copy paste from some text book but created specifically for each Duolingo skill. I'm 100% sure that you would make better progress if you read them.
I was doing Russian on the app. I posted the pictures in the link as proof. It's just not "official", hence I had to switch back to the site in order to progress to the next section.
Edit: I just tried it and it still works https://drive.google.com/file/d/0BzFZ7XZ-mS5dN2RZc1Fia2RLbWM/view?usp=docslist_api
