I started learning russian 50 days ago. I reached a point when my fresh account had 1600 words learned then it was russian 5 that there was part 16 that is missing one word and could not be completed that I press to learn it again in case the date gets wiped off but nothing worked. When I went back to my main profile the words went from 1600 to 1200 learned. For some reason now it matches the mobile application count that was always 400 less. This has totally put me down and I lost all my motivation to learn.
How is this possible? Can it be fixed? I am a premium user and I strictly use the website.
