It might be a "cookie security issue", like a wrong combination of secure and samesite value on the cookie.
You can try to enable "Secure all cookies" in Cookie Manager and see if the problem goes away.
You can also try this in Chrome developer tools (F12)...
- Reload the page (F5)
- Go to Network and find the response for the page. Does it have the expected Set-Cookie reponse header for the cart cookie?
- Go to Network and filter the responses by enabling "Has blocked cookies". Are there any entries on the list?
- Go to Application > Storage > Cookies > yourdomain.com and filter the cookies by enabling "Only show cookies with an issue". Are there any entries on the list?
If you can't find any issues then it might be a bug in DW which has already been fixed during the years that have passed since the release of 9.6.9 ;)
Try to upgrade to latest 9.12 and see if you can reproduce the issue.
Otherwise, I think you need to contact support, so that they can take a look at your website.
