As are most people, I've been having more and more issues using flash, not just with WGT, but with any other website that uses it. As I was researching the problem, I've learned that Google just published a report that within Chrome, Flash usage has declined from 80% usage tin 2014 to less than 8% today.
The article went on to say that Google would stop supporting flash as of the release by 2020, and even Adobe announced last year that it would stop supporting flash by the end of 2020.
Most systems are running on HTML5. I'm just curious to find out when WGT plans to overhaul their system and move away from flash.
