Site not updating
The Facebook crawler can be identified by either of these user agent strings: You can target one of these user agents to serve the crawler a nonpublic version of your page that has only metadata and no actual content.
Searching for downloads or for sources of a download is done over the servers.
You should also exempt it from DDo S protection mechanisms.
If content isn't available at the time of scraping, you can force a rescrape once it becomes available by passing the URL through the Sharing Debugger.
If left unchecked (with Software Update set to On), you will be notified when an update is available, but will have to manually complete the process.
The quality and performance of the software is not warranted for the applicability of any users.
JVC KENWOOD Corporation shall not assume liability for any defects, nor warrant anything other than is expressly provided in the agreement.
