Hi @caapri,
Thank you for reaching out to us for assistance. Please check your setting at WordPress Dashboard > Instagram Feed > Settings > Feeds > Caching. You may need to lower the time here. If the feed doesn’t seem to be refreshing according to the schedule set here, please try adding the property cachetime=30 to the shortcode you are using to add the feed to the page. So for example, if your current shortcode is [instagram-feed feed=1] , you would change it to [instagram-feed feed=1 cachetime=30]
This issue could also be related to the browser cache or OPCache in WP Rocket, as that usually has a separate setting than the standard caches.
If you need any further assistance, please send us a support request here and include the System Info from the Help page of the plugin settings.
Best regards,
Louis
