@TeamYouTube watch history has been wildly inaccurate. Videos don’t register as being watched most of the time. If I watch halfway then click another video, then go back, it starts from the beginning instead of where I left off.
iOS, iPhone X. I’ve been reporting it for a while now. I just tried uninstalling so I’ll see if that works. Side note, why are channel names no longer in the subscription feed??? It makes finding videos difficult.
