A Bug! The timestamps for the player in a browser and in an Android do not match!

Hello everyone!

I’ve found a bug.

At first, I imported a lesson, and on the web app I have corrected all incorrect timestamps. Then I learned the lesson on the web and checked all the sentences. They are okay. Finaly I downloaded this lesson on my Android. I wanted to repeat the one, but the timestamps are incorrect on the phone. Why the timestamps for the player in the browser and in the Android do not match?

My browser is Firefox

here the lesson is

Looks like you didn’t post lesson URL. Please do so.
Also, let me know if you noticed the same issue with any other lesson.

This problem is all lessons of my course. It’s already been moderated, so everyone can access any lesson.

Thanks, our team will look into this.

@zoran The timestamps match on my Android and Firefox browser if I use *.wav audio files

and the ones do not match if I use mp3

@michael214 Thanks for the feedback, I appreciate it.
