Is it working as it should?
I'm only able to proceed with solving tasks which are already translated to my native language (polish). I'm not able to see requirements of tasks in English. I can spent dark matter to unlock further lessons, but without any practice tasks. Is this app designed to work that way?

IntelliJ won't load excercises maybe language problem, how do I change System Language?
Hey, so I'm in level 5 now but never used IntelliJ, because it won't show the excersises past Level 2. Is that because my "Teaching Language" is German and the German translation stoppt after Level 2? Is there anyway to resolve this? Like how do I change the Language of all lessons to English?
