Problem: After upgrading to 2.3 SP03, certificate alias properties are empty in SAP Control Center.
In SAP Control Center, under Replication component, these properties are empty, and no default value is provided:
Solution: The certificate usage is not affected except on the iOS platform. The old E2E keys, HTTPS certificate and Relay Server certificate are still used. This arrangement is by design, because there is no corresponding alias in the keystore for these keys or certificates, and the runtime does not automatically import any of the old certificates to the keystore.
On the iOS platform, when the E2E encryption certificate alias is empty, the user gets a synchronization failure. To correct the error, import the certificate to the keystore, then set the E2E encryption certificate alias.
