I am currently running Android 9.0 (was seeing the same thing on 8.x) and I do not get prompted to save new credentials when I first log into a new website (chrome browser) or an app. All I can do is search. I have turned on accessibility and autofill.
1Password Version: 6.8
Extension Version: Not Provided
OS Version: 9
Sync Type: 1password
Referrer: forum-search:1password app on Android is not giving me the option to save new credentials in chrome
