Last last lesson of second part is not found

Hi, You are not able to continue, since you've reached the last part of the translated content. We only have a limited number of levels/lessons translated to Polish language at the moment. In order for you to continue properly, we will need to switch your account to the English version of the course. ​ However, please note, that you will not be able to view your old task solutions on the website once we make the switch. Therefore, please upload any required completed tasks to your project in IntelliJ IDEA, if you want to go back to them for reference. In order to proceed learning on the English version of the course, the subscription is required. ​ Please let us know, if you are ready to go ahead and switch the course language.
