Unable to add an additional G suite user via Squarespace

Site URL: http://www.fairyjobmother.co.uk

Hi there everybody!

I'm trying to add a user to my GSuite account ( note I can only do this via Squarespace as I purchased the Gsuite package via Squarespace). As soon as I enter the user details, enter my payment details and click to the final review page, the page keeps loading forever and never moves on the the final submit page. See attached screenshot.

Does anybody know why this is happening? Please help.

Thank you in advance.

Thank you @Paul2009

Also having this issue for one of my clients and it's impacting their business. Still haven't heard back from Squarespace support in days. This is ridiculous!
