I rewrite my post of my opinion about the new update of Italki, because the previous one was not really good. I will also tell about what I like about the update, not just the things what should improve.
Podcasts
Some of the Cantonese podcasts, the things are explained in Mandarin Chinese.
It is that I can understand Mandarin Chinese, but for other people who can't understand Mandarin Chinese, a transcription and English translation would be helpful.
Actually I like the display of the podcasts before the update more than after the update. The display was just like when you are searching for teacher, a bigger display. Now it is smaller.
Messages button
If you have read my previous post, I told that the messages button that has changed place, was not really practical in my opinion. But now I actually get used of it, so I don't care anymore.
Quizzes
It is not possible to see which vocabulary and quizzes (in the Discover section) a teacher has made, when going to the teacher's profile, only the podcasts you can see by clicking on the posts of the teacher in question.
In overall, a nice update.
