Bug description: Ever since updating to High Sierra, whenever I pause a lesson and go back to it, it will sometimes skip ahead or move back 2-3 seconds, and at the end of the lesson, the timer on the left hand side (that tells you how much you’ve listen to so far) will go like 10 seconds over the length of the lesson before ending. When this jumping around forward 2-3 seconds happens, the displayed time is different to the actual time (when compared to a downloaded version). Then after jumping around forward too much, the timer will jump back a few seconds.
