Autofill does not work on https://app.trulyfinancial.com/payments , Looks like 1password is not attaching itself to the input fields at all.
I tested on Chrome and Firefox, gott the same result. I used the "collect page structure" feature, it shows that 1password considers these fields as hidden. They are perfectly visible and are working manually just fine.
1Password Version: 8.2.2
