It's really frustrating when you have a perfect streak and making every effort to practice every day then suddenly for some unknown reason you get kick off the site during the practice dialog..., lots of buffering, the website logs itself off, It's as if its being remotely controlled. I immediately log back in, there's lots of buffering. Then finally when I'm able to log back in, the duolingo website will start you from the very beginning, not even giving you credit for the progress I have already made. Then I start over again just to get kicked off once again from their website. I notice this happens quite frequently after I have had a perfect passing score and streak.
I have no idea what causes this, but it is extremely frustrating. You get kicked, log back in, kicked off again, AGAIN, again...
