When using both the mobile app (iOS) and website on Win10 desktop, neither log-in when using autofill - they say the creds are wrong.
When I copy/paste the password from 1Password into the login form all works on both mobile app and desktop website.
On mobile I click the eye to see the password in the clear and it looks correct.
