EX-5s Bike will not run 'Update 2.5.8.4-mounted 149'

When I turn on the screen, FitOS says 'A newer version is available' so I select 'Download'. It then goes to the next screen where I select "Update Now to 2.5.8.4 mounted 149". It then flashes briefly to the update screen showing the progress bar but the download never starts and it just goes away leaving a blank screen behind. I can go back to the home page and try again but the same thing happens repeatedly. I have unplugged and plugged it back in multiple times with no success running the update.
