Unable to advance to the next lessons
I'm trying to get to Present and Demonstrative tense lessons for French but keep getting this error message that says "could not connect to duolingo. Please start session again"
If the problem persists, I recommend messaging bchan. Be sure to mention what operating system and browser you're using. (For example, I'm using Windows7, Chrome.) Until then, try emptying your browser, Checking to see if your computer needs to do any updates, then signing out and signing back in and trying the lesson over. Also, be sure that your internet connection is stable.
It sounds like an internet connection problem to me. But, I'm not a tech. You'll still need to let bchan know more about what you're using, as each app is a little different and the problem could have different causes. So, if it is a phone app, which phone. If you know what version of the app you have that would be great too. If it's a tablet, what version and make. That kind of stuff. :)
