Using the built-in iOS password manager, when I submit a login form in Safari that the password manager has never seen, I am prompted to save the login & password in the keychain.
It doesn't seem like 1Password is activated when a login form is detected. Is there a way to enable it? I have AutoFill on for 1Password only (I turned off Keychain AutoFill).
I reproduced this by deleting all my passwords for amazon.com and logging in, first with Keychain AutoFill (which prompts to save the login), then deleting the password, switched AutoFill over to 1Password, and log in again. There is no prompt to save the login.
1Password Version: 7.3.6

OS Version: iOS 12.4
Sync Type: 1password
