It looks that a problem is that server-side signal is slow. It mostly works for me. In order to confirm it, could you please attach password manager logs.

For this, could you please do the following steps?
1.Open chrome://password-manager-internals in one tab
2.Open the site in another tab
3.Return back to the first tab and copy/save the content  (it's Password Manager logs, no private information) and attach it to the bug

Logs with correct classification:

Captured password manager logs are listed below. Logs are cleared and no longer captured when all password-manager-internals pages are closed.

Vadym, can you take a look. This issue is still prevalent.

Hi Patrick.
Looking at the logs shared by Dominic, the difference in when Chrome recognises the form as sign-up (=no automated filling) vs. sign-in (autofilled) is indeed in the presence of server hints (which correctly say that "signup_form_password_" is ACCOUNT_CREATION_PASSWORD).

And also on my computer, this issue is not repeatable, probably due to fast internet in the office.

You could help us verify whether this is indeed the autofill server being slow by opening chrome://histograms next time Chrome autofills the sign-up for you and sharing the values logged for PasswordManager.TimeBetweenStoreAndServer. The values represent milliseconds between the request for server hints and the receipt of the server response. Currently, Chrome gives up waiting after 500 ms and fills without the hints. If you see values greater than 500 in the histogram, that would confirm that it's the server response delay which causes it.
