Hi Andy,

I verified with 2 fingers and observed that both Fingers Identity is
working fine, let me know if i need to provide any other info, it is not
working with single FP identify template on 22.04.
Does anything need to be changed from tod driver to support this feature on
22.04?

fprintd-verify is returning an error even with 2 fingers enrolled, but the
Login screen is successful with 2 finger enrollment.

if you can help to change my email for bug communication, can you add my
official email id: "<email address hidden>" to this list, as i was
suggested to use this e-mail for communication, i did change e-mail at my
profile, but this issue was created before it got changed.

fprintd-verify application log posted below: fprintd claiming FP verify is
failed, but login screen FP identify is working good.
