Thank you for confirming, @HLG.
As Timothy kindly referred to previously, 1Password for Android can only fill address and email fields from Identity items at this time. Your feedback is especially important to us, so I am more than happy to pass your input along to our product team for us to expand and optimize the filling experience for Identity items.
In the meantime, I'd recommend using the https://support.1password.com/android-autofill/#get-help feature for fields that we are not able to fill at the moment.
Let us know if you have any other questions!
