Hey, AntonyB! Thanks for sharing those details with us.
Are you using Gboard as your on-screen keyboard? We discovered an issue with the latest Gboard version on Android 12. We've contacted Google about the issue since it is due to Gboard itself rather than apps like 1Password. In our testing, other keyboards like SwiftKey show inline suggestions as expected on the password field. Until the Gboard issue is fixed, a workaround would be to disable the suggestion strip in Gboard (Settings > System > Languages & input > On-screen keyboard > Gboard > Text correction > Show suggestion strip) or enable another keyboard on your device (Settings > System > Languages & input > On-screen keyboard > Manage on-screen keyboards).
Let me know if you're experiencing the issue with another keyboard.
