NEW CodinGame Sync 1.0.4: The update will be automatic. If a problem occurs using CGSync, please verify that the plugin and the application are both up to date ( v1.0.4 ) in the chrome://extensions/ tab.
You can wait for the automatic update or force it.
To manually force the update :
Head to chrome://extensions by either right-clicking on an extension and choosing Manage extensions, or just typing it into the location bar. Once there, click the Developer mode link on the right-hand side.
And then click the Update extensions now button.
