I am trying to park domains on Firebase. I am facing an issue that may actually be a UX / copy issue on the firebase console. 

I added a TXT record as indicated in the firebase console in my DNS records. These can take a while to propagate. However the firebase console throws a messagin indicating :

We couldn't verify your domain [DOMAIN HOST]. Please check your settings and try again.

It seems misleading to indicate that outright and not allow for a propagation time in this message. Or may be I am doing something wrong. because I changed the TXT records a week ago and I still can't verify this domain. 

I was able to verify my domain after I saw the above message (the previous version of it) after allowing one day. This is even more confusing given that the UI looks like a wizard with a next step that seems like it is something that needs to be done in one sitting. 

Questions:
1. Are my assumptions correct. Could I be doing something wrong? 
2. Is there anything I can do to troubleshoot verifying the domain that has been awaiting parking for over a week?

Hey Raj, a few answers for you:
  1. DNS should not take a week to propagate. If it's still failing after 24h+ something else may be wrong.
  2. Some debugging tips:
    1. Run `dig your.domain.com TXT` and look for the verification record. Make sure it's present.
    2. Make sure the verification record is on the domain specified in the console -- when adding a subdomain, we still generally request verification of the apex domain (e.g. mydomain.com not sub.mydomain.com)
    3. If you still don't know what's wrong, contact Firebase support with the details and we can help.
I've filed a bug internally to see if we can improve the error messaging here.

I'm PE in Webmasters product forums. We often have question about DNS verification so i will share other debugging tips:
1. It's not important DNS propagation between all DNS servers. You need to check Google servers specially. Here is how to check TXT record that Google knows:
2. You can update Google DNS information for some domain with flushing it:
this will force remove information, so next request for domain will reload information.
3. You can also use nslookup:
nslookup -type=TXT mobiliodevelopment.com 8.8.8.8
and set force to use Google DNS. You also can use 8.8.4.4 too and there are some IPv6 IPs too. If you remove 8.8.8.8 from the end of command line will use system dns for resolving.

I hope that this will help you!
