How do we get better fills on android?

I am a lastpass user that is trying out 1Password because I got access to it via EERO+. On paper, this looks like an upgrade. It handles authenticator TOTP, it has a shared vault instead of having to send and accept individual sharing password requests, it has better security, the desktop app works with browser extensions etc. 

But the major problem is, it will not fill things on android as well as lastpass. It rarely if ever fills a username which means all logins that are 2 step - fill in username, click next, fill in password - I have to go to the app and search to find the username. And when it comes to the password field, it's less aggressive than lastpass. 

Maybe this is a design choice but as much as 1password seems better (and free with eero+ to boot) it's a deal breaker for me. I have to balance convenience with my security and especially so for my non techie wife, I can't make her work flow any harder and to share passwords we have to use the same password manager -  and it just makes sense to do so, if I become incapacitated I need her to know how to get into mine (and yes, having had a heart attack and a cardiac arrest and bit the dust for 3 minutes before being revived, I worry about this).

So I would like to ask is there any way to make 1password more aggressive at filling in boxes? I'd rather have it ask me for things it shouldn't (like lastpass) than the reverse. If some people don't like it, make it configurable thru settings. 

I would like to switch to your product but the way it works now, I can't.
