In our Sitecore 9.2 PaaS solution, we are using self-signed client certificates and have added the AppSetting AllowInvalidClientCertificates=true
to all xConnect roles as well as the PRC, CD and CM server.
However, these certificates are about to expire, so we are wondering if we have to renew them or whether the setting AllowInvalidClientCertificates also enabled expired certificates to work?
