Hi there,
I'm trying to add custom emails and I had to go through the domain verification procedure.
However, after I added CNAME & TXT records to my domain, it passes the validation for a short period of time and then all the records became invalid.

I've seen similar issues in the forum like this but it looks like my issue isn't fixed.
I also tried to use https://dnslookup.online/txt.html and I didn't see any issues there.
Update: The TXT record goes invalid as well now.
