Descriptive Problem Summary:
If, due to a lack of Flash, a ad cannot be displayed, it displays a permanent error message that prevents use of the web client. Since some browsers, such as mobile Chrome, do not and will never support Flash, the web client cannot be used on that browser.

Since Chrome is one of the only Android browsers to support WebGL, this is a serious barrier to use of the web client on mobile platforms.
Numbered Steps to Reproduce Problem:
1:On a mobile device running android, download and install Chrome.
2:Start Chrome.
3:Enable WebGL in the chrome://flags menu.
4:Attempt to join a game using webclient.


Expected Results:
Game is successfully joined and playable.
Actual Results:
Client appears to start, but is permanently obscured by an error message stating that a Flash ad could not be displayed.
Does the problem occur:
Every time? Or how often?
Always.
In other games?
In all games that support the webclient.
In other user accounts?
I have not tested different accounts, but presumably it will occur in any account that displays ads.
On other computers?
Any mobile platform browser using Chrome or otherwise lacking flash, yes.

When does the problem NOT occur?
Browsers that support Flash.

Workarounds:
Use a browser that fully supports Flash, HTML5, and WebGL. On some mobile platforms, no such browser exists.
