I have just lost my streak ;_____;
I was dumb enough to forget to do the lesson today, and when I realised it, it was already too late. RIP my streak, gone but not forgotten :`(
I had the same thing happen a few weeks ago. I had a day off of work and didn't do it when I normally do on days off, and totally forgot! I had been doing it every day since it went into Beta! I was so bummed!
