@ally-sassman thanks for updating these screenshots. I'm not sure the new image for the attributes tab is actually for the attributes tab (src/images/errors-inbox_screenshot-crop_error-context2.webp). Could you confirm?

Also, I'm not seeing this image imported or referenced in the doc: src/images/errors-inbox_screenshot-full_users-impacted.webp
