IOS not using Face ID on non-Safari browsers?

I've got Face ID turned on to open 1Password.

I just now noticed that when using DDG, Edge, Firefox, when I get to a login page, and select to autofill the info that it opens 1Password app just fine, but it makes me type in my 1Password password EVERY time. The 1Password app login screen says, "I need to enter my password once before it can use Face ID", but I keep doing that and it still makes me type it in every time I try to use it.

I know I have it set to re-prompt me to re-enter every 14 days, which I'm used to happening, so that's not the issue.

I don't recall this being an issue before, it just became noticeable to me now.

I don't normally use Safari, but tried it there just to cover all cases, and in Safari, the Face ID works as expected. It opens and auto fills just fine. If I just open the actual app itself, the Face ID works fine too.

I'm quite sure that Face ID was working automatically in DDG and EDGE previously, as I use those as my primary browsers and don't think this was the experience I had before.

Theories?
Thanks in advance.
