This issue can be caused by the "Cloaking" setting on your custom domain. This will cause the page to load in what's called an "Iframe" which for security reasons, we do not allow.
Switching this off will resolve the issue with adding items to cart, but it may not retain your custom domain once a customer visits the site.
It would be worth emailing your domain provider to see if there is another way to redirect your domain and to retain the custom URL once you land on the site. Or you could log in and take a look at the DNS settings yourself to see if you can deactivate "Cloaking or Masking".

We have no control over your custom domain settings, so this cannot be actioned from our end, but we are also happy to help.
