How long does it take for Jira Cloud to verify our domain?

[Eric Johanson]

I am trying to get our domain verified, so that I can move all our users over to "Managed Users".  To verify the domain, we are putting a TXT record in our DNS server.  I put the TXT record into our DNS server 3 days ago.  I confirmed that the TXT record is present by using the mxtoolbox.com site.

The problem is that Jira's "verify-domains" page still shows our domain as "Unverified".  I have waited 3 days and there has been no change.

Do I need to just keep waiting?  Or am I doing something wrong?
