On PC in Chrome I pause a course and then hear the audio a couple seconds later, when I unpause, it shows the correct solution as if I made a mistake.
Are you using the “Timer disabler” user script?
As it seems the “doubled workaround code” can not completely (100%) cancel the ticking timer anymore and there are now some rare side effects with pausing the course.
If you hit the pause button when you have chosen the right answer (text field is marked green) it works a bit better than when you pause the next unanswered question.
I don’t, only the typing only one.
