Good Learning App

Good Learning App, but why these days I don’t see the translate on the youtube?
And on iphone, when choosing a word, click on the speaker to pronounce, only when wearing headphones will there be pronunciation, and without using headphones, there is no sound. Hope the author adjusts, thank you very much!

It’s not working perfectly

Hi. It’s been 3 days since the app is not working well. It’s not showing subtitles at all. Even for the videos that has oficial English subtitles available. 😢
