This is an unusual, pretty darn mild, and actually kind of amusing bug. When I look at a video in My Mix the caption of that video appears on other videos for an undetermined amount of time until another caption from My Mix gets stuck. It only seems to be coming from My Mix videos, and the stuck caption only appears on other videos when I click to comment on them. I’ve taken screenshots of a random example to better explain.
Original video from My Mix
Videos in two different sections that gained that caption
So not top priority stuff, but kind of amusing, kind of confusing. ((For awhile I assumed everyone was using the same captions and I thought I had missed something))
