If one of your emails has been found in a data breach in Pass Monitor, Proton Pass will currently only show logins where you saved your email in lowercase.

For example, if I have a login saved as My.Name@example.com, Proton Pass will say "Breaches detected for my.name@example.com" and the "Used in" section will currently be empty because it didn't match My.Name@example.com.

This is a request to show all matching logins in the "Used in" section regardless of case.
