New, not getting any auto fill notifications

I have not used a password manager before. I am on my Android phone, I have the app. I have followed the instructions to export Chrome passwords and imported them into my vault. I have tried several website and apps that require login and I am not getting any notification or option to use bitlocker on auto fill password. I have enabled auto fill in the setting section of the app. I have read the help on autofill but I still don’t understand what I need to do to make this app work. Can someone help me?
