Using Bitwarden on Vivaldi or Opera on Android

I’m trying to switch from Chrome to Vivaldi or Opera on Android, but to leave Chrome behind I need a solution for logins, personal information and credit cards.

I installed the Bitwarden Android app, added a couple of logins, a credit card and one of my addresses. But so far I’m not getting the behavior that I get in Chrome with its own.

Using Chrome and forms filler, I type the first letter or number of a form and everything gets populated. With Bitwarden and either Vivaldi or Opera, logins do come up on my keyboard, but nothing comes up in the credit card or personal data fields.

Is there anything to do or is this the expected behavior?

Thanks!
