In my UWP project recently certificate is expired. Now I'm creating the certificate using the below reference link. But still, I'm facing the below
"> This app package is not signed with a trusted certificate. Contact your system administrator or the app developer to obtain a new certificate or app package with trusted certificates.
"

Please help me. How can I resolve this issue?
