I lost a day where I practiced twice! This broke a long streak.
I had practiced twice on Friday. I checked and saw the green F. But when I practiced on Saturday, my Friday was gray and my long streak was broken. This has happened before. Anyone else seeing this?
I always get onto the website and reload the entire page and check to see that I have a green checkmark on the streak flame. So far (touch wood) that has never failed me.
Make sure the menu bar reloads; type "www.duolingo.com" into the URL box in your browser and hit "enter" if you have to. The app/browser will show your activity in the user interface (on the screen) but the only way to be sure it's registered with the servers (that I know of) is to reload the web page and double-check.
Agree with the advice above. However, something is odd with this person's profile: The Daily Goal is set to None. I haven't see that before.
