404 error when collaborating on Express document

[default35289905kzet8n]

I was shared a layout to my email address commander@cvma48-4.org, and when I click the link I get a 404 message like in the attached screenshot. I have tried unsharing and resharing it, I have also looked in the Shared with you folder but cannot see the layout. The link provided in the email is https://postoffice.adobe.com/po-server/link/redirect?target=eyJhbGciOiJIUzUxMiJ9.eyJ0ZW1wbGF0ZSI6ImN...
