I lost my progress!

I lost my progress!


I started studying from here on 13.09.2017 ( yesterday ). I logged in today, just to continue studying and I realised, that all my excercises, which I’ve done ( around 50 ) are lost and my progress is lost. What I could do?

It’s also very strange that I started where I left the last exercise, but the counter in the top right corner is reset to 1?


This must be the 98th post by someone saying they lost their progress. Did none of the other threads help?


It happened to me as well, I simply go to map manu and start from unfinished exercise.
