Ios app player controls from lock screen not syncing with app

If I attempt to control sound on the ios app from the lock screen (play, pause, etc) the app seems to fall out of sync with what is actually happening.

So for instance if I press play from the locked screen, the sound will actually play but when I open the app it will show the sound is paused and no progress through the file will be shown.

Thanks for reporting the issue. We will look into it.

Hi again here! We have a few additional questions that will help us figure out the issue since we are unable to reproduce it on our end.
Does the issue occur when you are listening to the playlist or within a lesson? Do you minimize the app too or just lock the screen?
A video would be great if you can trigger the issue quickly. You can send it to support(at)lingq.com

Thanks!
