SSL expiration details are missing in Command Center for Preview instance.
Reproducing the Issue
1.Login to command center.
2.Click on Settings
3.Verify the SSL expiration details.
4.Details are missing.
If the site is using a certificate provided by SAP so there is no site certificate to expire.
This is the expected behavior for the site created in preview instance - where the certificate is provided by SAP and no seperate installtion is required for the same.
