Web Practices Do Not Count?
Does desktop practices count? I practiced yesterday via "Strengthen" button and my streak is still zero.
Your extended user profile shows your last activity was on the 10th (2 sessions, 19 & 28XP), so I can only conclude your practice yesterday somehow wasn't "submitted". Maybe you didn't press "Continue" after the last question?!? I assume you have working internet on your desktop? Also, you can check whether you have reached your daily goal by making sure there's a green checkmark on the flame in the top bar.
