Marketplace - can't verify via TXT field

There are supposed to be two ways to verify domain ownership -

  1. Change nameservers to nameservers. This makes the domain itself resolve to your Squadhelp landing page.

  2. Add a TXT field containing a specific alphanumeric string to the DNS for the domain. It’s easy to do this across multiple domains at my registrar, and I don’t want to use the Squadhelp pages for my domains yet.

The problem with method #2 is that it IS NOT WORKING. I added the TXT field to all of my domains and none of them are verifying. I hit the verify link over and over every few days.

Can someone either fix this or provide better instructions?
