The YouTube progress bar in Dark mode is now white on some Android phones
When watching in landscape orientation, you don’t see the progress bar unless you tap the screen, and then it will appear for a second. The progress bar in landscape is in red and hasn’t been changed-at least not yet. And we need to point out again that the change to the color of the progress bar in portrait is seen only when you are watching YouTube in Dark mode. In Light mode, the progress bar is red so it can stand out. It makes sense that a white progress bar would be more easily seen with a dark background.
