Audio just stops.
Not too often, but occasionally I'll be in the middle of a lesson, and the audio will simply stop. Sometimes I am able to bypass this issue for the remainder of the lesson by copying and pasting the sentence or word into google translate to be read aloud. However, if a question arises which offers no text, only audio, I have no way to continue - lesson over. This issue is for the PC version, not mobile. Is there any way to solve this problem?
