Currently, you cannot pause, revoke, or regenerate the link. Anyone who has the link can access it. To close a public page, you can only delete it or remove the catalog from the visible objects. Public pages are not indexed by search engines.
The language is determined by the seller, not the visitor's browser. Each public page has one language setting (Traditional Chinese, Simplified Chinese, Japanese, or English). The shared link format is /public/{language}/{ID}, with the language specified in the URL. Visitors do not see a language selection menu on the page.
If you change the language of a public page after sharing, the previously sent links will still use the old language. You need to copy and resend the new link to customers. To serve customers in different languages, create multiple public pages and set the language for each one.
