To view your existing certificates, first log in with your NICEIC details. Tap 'View Existing' from the Dashboard. You will now be able to view previously created certificates.*
Within this section you can also lock a certificate to your device to prevent editing by others while you are still working. To do this, tap 'View Existing', then tap 'Take Certificate'. To unlock the certificate from your device, follow the same steps as before but this time tap 'Release Certificate'.
*You will only be able to view data which has been synced to your device.
