We're still experiencing audio sync errors during playback, this has affected a ton of our videos, not all. We thought this issue was fixed in June 2018? wondering if we're doing something wrong? Please help @YouTube we need this resolved as soon as possible.
That's odd. Just to confirm, have you checked our Help Center article which has info on how to troubleshoot audio - video sync issues: https://goo.gl/WBdmsM ? Hope this helps.
