Thanks. I'll cherry pick this back to release/3.0 and contact shiproom.

Is this fix already present in the current 3.0.0 NuGet?

@StefH yes, see #13480

I have the same issue getting error "Microsoft.Extensions.Options.OptionsValidationException: The 'Instance' option must be provided."

It works with ".AddCookie()" but failing with ".AddOpenIdConnect()"

services.AddAuthentication()
.AddOpenIdConnect("okta", "Okta", options => Configuration.Bind("Okta", options));
.AddAzureAD(options =>
{
options.Instance = "https://login.microsoftonline.com/";
options.Domain = "tenant.com";
options.TenantId = "xxxx";
options.ClientId = "xxxx";
options.CallbackPath = "/signin-oidc";
});

@ivan-sedlak OIDC is covered by a different code path.
