Verifying and authenticating domain on Mailchimp

Domain verification and authentication problem on Mailchimp.
All necessary CNAME records have been entered.
Verification must go through that record.
There is no publicly available record as seen in the image.

The best feeling is when you find a solution yourself.
In the section DNS > Settings : CNAME Flattening
should select “flatten CNAME at root”.

Good catch! Ya the flattening can often cause issues with CNAME records used for verification.
