I put "zaczęłyśmy produkcję" and it told me I had a typo in my answer. Can someone explain why?
Maybe they didn't add this sentence. You should report it.
Okay, just wanted to check I hadn't made a mistake. Thanks!
Could I use zaczynaliśmy here?
No, that would be like "We were beginning". I think it could rather work only in some memories, like "I remember when we were 20 and 'were just starting' our work in KFC..."
Zaczęłyśmy produkcję is rejected? Perhaps the conjugation of zacząć in wiki dictionary is incorrect?
