I have 3 players in my club that have messaged me that Flash id dead for them already 1 of them let his PC update EDGE browser said "Flash no longer Available" or "Flash not allowed" He said EDGE now looked entirely different..
Have them try this, this is Torch
Version 220.127.116.113 (Official Build) (32-bit) works quite well with flash. I run it on win7, pretty sure it will run on 10(maybe, at least until the next 10 update) I can't try it on my gaming rig which is running 10 as I don't even have flash installed on it.
I just tried on this machine(win7) running a beta version of Edge, had to tell it to allow flash and run my version as it is an outdated version of flash, seemed to work alright, but with the Torch version, I had to tell it to run flash the first time and never again, even when I come back to WGT, unlike Firefox and Chrome, that you have to tell it to run every time you visit the site.
