Issues on using gmail business email to login

[zijiaZ]

Hey, I am seeing an issue when using gmail business email, which is reproduced on the latest version: 6.0.2. I use SPM, and calling - (void)signInWithConfiguration:(GIDConfiguration *)configuration presentingViewController:(UIViewController *)presentingViewController callback:(nullable GIDSignInCallback)callback;

Login using gmail business email neither success nor return an error first time on a device, it only return an error on the second, third time, and so on.

But the gmail business email works well on simulator. any thoughts on why it did not work on a device, or why it did not return an error first time? Thanks!
