Once your learners have synced, you'll be taken to the 'Finished' panel.
Refresh the browser page to immediately update the user and class information in the Admin Hub.
To check that your account has synced correctly, go to the purple Classes tab. The registration groups you've chosen to sync should have an unbroken chain link in the 'Synced?' column.
Next, go to Pupils > With access. Newly imported learners should be placed in this tab automatically and have an unbroken chain link in the 'Synced?' column.
If things aren't looking quite right, see Troubleshooting your MIS sync.
