Why are my posts' Featured Images missing from my RSS feed?
By default, WordPress won't automatically pull your post's Featured Image into the RSS feed. This can result in images not appearing on your Bloglovin', Feedly, or other RSS-based accounts.
To make your RSS feed include your images, we recommend installing & activating the plugin called Featured Image in RSS w/ Size and Position.
Please note: While this plugin should immediately help your RSS feed recognize and include posts' featured images, it can take some platforms (like Bloglovin', Feedly, etc.) up to 24 hours to re-crawl & scrape your site again for updated data.
