Streak lost for nothing
Yesterday morning I was on a 204-day streak, I also had bought a streak freeze (just in case) and my account was totally fine. What happened yesterday night? Right after reaching the daily goal 1) I lost my steak (it suddenly became 1 day), 2) I lost my freeze, 3) my e-mail address became non-verified. What happened today? 1) Duo offered me to buy a streak repair (haha, no way Duo), 2) after reaching the daily goal my streak is... again 1 day! ))) Perfect motivation Duo! Keep working. You are the best.
By the way I used to lose my streak before and I know what it looks on the graph. The lost day's point is empty. My graph of the recent days is perfect. I reached my goal every single day! And I will not pay anything!
If you think this was a bug, you can contact Duolingo here: https://support.duolingo.com/hc/en-us/requests/new
Also, note that streak freezes don't work if you buy them on the same day you use them.
Thank you for the link!
As for the freeze, I bought it several days ago. Anyway, I did not need the freeze to support my streak yesterday just because I met the daily target.
