My game has a google login feature in it. This was done using the authentication firebase plugin. When the game is not hosted on the arcade, it works just as it is supposed to. You can find that here: http://bit.ly/spacearena. However, if it is hosted on the scirra arcade, the window pops up but it doesnt let me click an account to log in with. You can find that here: https://www.scirra.com/arcade/action-ga ... arena-5048. I think this is a website issue because when I open the chrome console it shows "Blocked form submission to 'https://accounts.google.com/AccountChooser' because the form's frame is sandboxed and the 'allow-forms' permission is not set." This is a major part of my game and allows for cross-platform syncing.
