Hey,
I’ve had this consistent problem or maybe it’s misunderstanding. Sometimes I’ll listen to a lesson of average length of 10-15 minutes and receive no coins when completed. This usually happens on YouTube imports. I’m not lingqing or marking known words, just listening as complete other household or work chores. Is this right or is this a bug. Also noteworthy I receive the coins if I listen a second time. Seems a bit odd or maybe the algorithm is encouraging more listening.
