I have same problem iOS 16.1.1
Orion 1.2.4 (2) (WebKit 8614.2.9.0.10)
iPhone 13 Pro
It appears on a few websites but on most websites I don’t have the iCloud passwords
Example websites it’s not working at:
https://auth0.openai.com/u/login/
https://accounts.google.com/v3/signin/identifier
https://twitter.com/i/flow/login
Where it’s working
https://login.fastspring.com/identity/auth/login
https://m.facebook.com/
Just a hunch but it seems to me that it’s WORKING on websites where the passwords have a “list” of websites its attached to in iCloud and the actual website im looking at is NOT the FIRST on the list.
And when it does NOT WORK then the actual website is FIRST in the domain list.
How it looks when it’s working vs not working
