Autofill on Android 8not working (new user)

I have Android 8 on cell phone with current BW installed a couple days ago. In the BW Settings I have AUTOFIL Enabled, but when I (for example) launch Brave browser and go to to login with the MS login screen, there is nothing there at all from Bitwarden - no prefilled userid, no Bitwarden icon. What to do?

Also noted that when I have BW open (on phone) and use it to launch, that BW does not auto-log me in to amazon and also does not populate the userid or password fields with anything at all.
