I believe that it is technically correct, just a bit weird. The way it's worded sounds closer to answering someone.
"Go to Russia." "I already AM in Russia!"
If you were to vacation in Russia and message someone back home to let them know you arrived earlier than expected, you probably wouldn't use "I already am in Russia" but rather, "I am already in Russia."
Agreed. It follows the exact word order and while I feel like it's a bit awkward, I'm almost certain it's proper English. Like if someone said "go to Russia" when you're already there, you might say (in a bit of a whiny voice) "I already AM in Russia!"
Edit: After I posted it, I read the other response and chuckled that I used literally the same example of when it might be used.
Are tips and notes available on the mobile app version by any chance?
I have seen them mentioned but have never seen these notes, but have also solely used mobile version and will be unlikely to deviate from that practice.
As I'm usually not doing this at home. Just curious I've simply assumed it isn't available anywhere on the mobile app so I've dealt with it by simply learning from my mistakes and comments.
I actually am on the mobile app looking at the comments. Once done a question, by the continue button is a sort of message icon. Click on that!
And when I dictate Russian, I find that Duo understands в, всё, etc., a lot easier or more accurately if I pronounced it "wrong" by using a fairly hard "vee" sound. If I use the "ffff" or "ffss" or "ssss" sounds I sometimes hear in the audio, I get the dictation "wrong". And I recalibrate my mid-range quality Sennheiser headphones fairly often. Not the best, but a very, very good set of headphones.
