WA Chrome Fix

On your computer, open Chrome. 
At the top right, click More Settings. 
At the bottom, click Show advanced settings. 
Under "Privacy," click Content settings. 
Find the "Flash" section. (should be 4th or 5th down the list)
If you trust the websites you visit and want videos, animations, and games to be playable automatically, choose Allow sites to run flash.

If this fix doesn't work, try contacting customer support. You may need to uninstall Flash then reinstall it or delete saved cookies/flash sites.
