You lost your wager
I got this: "You have lost your wager. Better luck next time!" And I lost all my day steaks, what is happening?
I have the same problem. E.g. yesterday I did my exercises early in the morning. Today, when I wanted to practice again I get the communicate that I lost my wager and my streak. And this is not first time when it happens :(
Did you forget to study/practice? You have to earn at least 1 XP per day in order to maintain your streak.
insted of one every 10 days, you have to keep up your streaks for 7 more days for 10.
