Google Sign-In is not supported.
Google Sign-In has a built-in mechanism to detect and block automated operations, making it currently difficult to test with Autify.
However, you can build automated tests by utilizing the Static IP Address option and implementing a workaround, such as displaying a simple login mechanism instead of Google Sign-In when accessed from Autify. Please consider this approach!
