Rss not updating
Moving a feed item or post to the Trash will not permanently delete the feed item or post, meaning that when you try to re-fetch the feed source, the trashed feed item or post will not be re-imported since it still exists on your website.
Always check your Trash folders for any imported items and posts and make sure to permanently delete them before attempting to re-fetch the feed source.
It is often the case that your cron jobs are either stuck, blocked, or not scheduled properly (click this link to understand how to check).RSS Feed publishers can specify the maximum frequency at which a check for new postings should occur. For example, an RSS Feed might have a maximum polling frequency of 60 minutes — this means don't check for updates multiple times per hour.Important: Some publishers strictly enforce these limits.If you check for updates more frequently than the specified limit, the RSS Feed publisher can temporarily or permanently block your access.Neither Microsoft nor Outlook can assist you if your access is suspended or banned by an RSS Feed publisher.
