@farat-aydan The way I understood it, is that Unlimited means you can continue to use all the existing features (which vary across languages, at the moment). So basically, what you see now is what you saw on 31 December.
Had you not purchased Unlimited, you would now have a more restricted experience, with fewer total words and fewer new words available per day. And I assume they are continuing to add other features, so that all languages (probably except for the mini course in Estonian)) will have the same or similar features in the end.
As it is now, I have more features in Spanish and French than in Russian. But I'm expecting this to evolve during 2018.
