Application @@ndroid test server sign up page

I'd go to the Menu>Help button in game and see if they'll give you a link. It takes a day or two to get them to respond but I bet they help you resolve it. The good news is that once you've done it once, you'll keep getting the invite every test server going forward. I see the email now and don't even open it, I just go to the test server war robots app and click and it says "would you like to update?" and when you do, you're set for the next test server.

good luck.
