Having major troubles with getting a progress bar to follow a video duration in React Native. It doesn't appear that the progress bars want to re-render.

My code is rather long, so I've put it into a Gist: https://gist.github.com/Jamesking56/7775eb32eba14305d1c2c3cbdbf59333

Any ideas how I can get the progress bars to follow along with the videos?

Cheers.
