I'm typing the sentence correctly and it keeps saying incorrect and won't let me move on !
That's strange. Did you check twice to see if it actually right?
I typed ‘taky nie’ and it marked it correct. Seems a little too lenient, Same with several other questions.
Without even saying that it's a typo? Could you please provide a screenshot next time?
The listening exercise is broken. She only says Tak but the correct answer is Tak i nie
The normal speed audio is fine, but the female slow audio indeed missed "i nie". I disabled the listening exercises and I will investigate it further.
EDIT: Should be fixed now (20.10.2020).
I was in polish mode so i wrore "yes i no" instead of "yes and no" hehe
