Domain verification failing

Hi, I’m having trouble verifying domain ownership of a 2nd domain we own. Our 1st domain is verified - everything worked correctly. Here’s what I’m trying:

1. Company admin > Settings > Domains
2. Click “+ Domain”
3. Copy the “figma-domain-...”
4. Add it to our domain’s main TXT record (along with the other values there) with our DNS provider. Wait a few minutes until it says it’s live/in-sync.
5. Come back to Figma > finish typing the domain name in the dialog that’s still open > click “Verify and add”
6. Error:  “Unable to verify domain”  “We were unable to verify the following domain”
