cannot log into self-hosted instance in the Android app with a passkey

i should be prompted for my passkey, which i can then select and be logged into my account.

i am prompted for my passkey, which i select successfully. i then presented with an error message "Passkey authentication failed". i am not logged into my account.

in the video i show myself logging into fluxfur.com in a web browser successfully, to prove that my passkey works. then, i do the same through the Android app, and the described bug occurs. not sure if i remember correctly this bug might have been around for at least two months; ever since i first joined fluxfur. i only realized nothing has been reported yet when i was reporting a very similar bug. but maybe the bug was different? i think when i first encountered it, i might have gotten an error message like the one described in this issue? i think, perhaps, Bitwarden rejected my login? like is shown in the second video happening in a different app? and i probably didn't report it because i assumed that was FluxFur's fault, but they've fixed it, and now the ball is in upstream's court?
