Login failed by WebView2 JavaScript?

[kiyoshi_miyake]

I try to login automatically by WebView2 JavaScript like below.

webView2.ExecuteScriptAsync("document.querySelector('#username').value = 'xxxx';");
webView2.ExecuteScriptAsync("document.querySelector('#password').value = 'yyyy';");
webView2.ExecuteScriptAsync("document.querySelector('body > div.account > div > div > div.account-login > form > fieldset > input.splButton-primary.btn.btn-primary').click();");

The code sets username and password correctly and click the "Sign In" button fine. However, I got "Login Failed" error.

Is there any tric to avoid auto login???

I am able to log in successfuly after just press "TAB" keys many times and click "Sign In" button without any change of username/password. it confusing me more...

@kiyoshi_miyake - Try adding time delay.

I hope this helps!!
