Trouble setting up Gmail logins with Bitwarden on iOS

I’ve been using Bitwarden for the last couple of months and I’ve had nothing but problems trying to get my Gmail logins working on my iPhone.
Autofill almost never shows my Gmail login, even though it’s saved in my vault.
Sometimes it tells me “No items to display.”
Recently, when I tried to switch to passkeys, Google just says “You don’t have any passkeys saved for this website or app” and points me to Bitwarden — but Bitwarden says I don’t have any passkeys saved either.
At this point I don’t know if I’m doing something wrong or if Bitwarden just doesn’t fully support Gmail/passkeys on iOS yet. Has anyone actually gotten Gmail working smoothly on iPhone with Bitwarden? If so, what exact steps did you follow?
Thanks in advance — I’d really appreciate any guidance because this has been incredibly frustrating.

I can’t add much as unfortunately I’m not an iOS user… you are familiar with that “guide” here: Autofill From iOS App | Bitwarden ?
