- Affected accounts can’t manually advance video playback.
- Logging out or using incognito mode offers a temporary fix.
- The root cause may be tied to experimental YouTube flags.
YouTube long ago evolved to become so much more than a place for entertainment, and whether you use it to get your news, discover fresh recipes, or learn how to complete projects around the house, it’s an invaluable repository for millions of users. Sometimes you don’t realize how much you rely on something until you lose it, though, and that’s exactly what we’re thinking about today as some YouTube viewers find themselves confronted with a confusing bug that prevents them from skipping ahead in videos.
Affected users have been sharing their woes over on Reddit, with an experience just like the one StormerJack describes: you go to advance your video by clicking on the timeline, and instead of jumping ahead, the player rewinds all the way back to the start. When mousing over the timeline, instead of seeing the actual position in the video, you’ll get a bizarre “-NaN:NaN” label.
