Due to a fat fingered mistake, I removed the link between my Zoho and AD account. After this the AD sync for users stopped working. When going to Enrollment > Active Directory, my domain is shown as integrated. But when I click the finish button, I I just get brought back to the same screen. I attempted to start over by removing my domain from the zoho business account and by removing the enterprise app from the Azure AD portal. The domain still shows as integrated though. 

I can't seem to find a way either re-link the accounts or to start from scratch.
