Very disappointing that they didn't solve the online gaming bug!! – Chain Reaction 2 : Online Multiplayer Review

The game is GREAT!! The only issue I had is when trying to play online, as soon as press the option apears a Google error screen with the text "403. That’s an error. Error: disallowed_useragent Google can’t sign you in safely inside this app. You can use Google sign-in by visiting this app’s website in a browser like Safari or Chrome." I think the problem is that I have an iPhone, maybe they didn't worked the Apple Game Center properly...
