Connecting a Domain: Squarespace still showing "pending domain owner verification"

I have followed the instructions to connect my domain hosted outside of Squarespace by following the guide here: https://support.squarespace.com/hc/en-us/articles/205812378-Connecting-a-domain-to-your-Squarespace-site

• I've added the unique code pointing to verify.squarspace.com, the www pointing to ext-cust.squarespace.com and added all of the additional A records. 
• In the Domain Settings, the domain says "Connected" and SSL certificate status is "Active".

Yet I'm still getting the message pending domain owner verification when I go to my website (http://www.apeiron-bio.com).

• How long does the verification take?
• Do I receive an email through my domain host that I need to verify?
• Anything else I should try?

Any help would be appreciated.

The site looks fine to me now.
