Just found how to input bugs. I needed to be logged in. I though I was logged in since I was able to do the lessons. Not sure if that’s another bug.
I’m using the app on my iPhone. After the audio lesson, Aula de História, there’s no way to move forward to the next lesson.
I also tried to leave a comment, but that didn’t work. I’m getting an error message that requests an email, but there was no place to put an email.
