If anyone can not see the highlighter even after upgrading the android version please do this - During the video just tap the left side of your screen 3-4 times after that video will go backwards for about 5-10 (2 taps= 5 seconds) seconds after that you can see the highlighter, this trick worked for me evrytime...
