We have not added any PHP code to increase the RSS feed refresh/cache time. Please let me know how can we fix that as we need to use google news feeds on this.
I have checked again and again there is an issue. Please have a look at the screenshot and let me know the best method if the issues again and again https://prnt.sc/ne6tIxgY6prD
Is the plugin updated as per the last request? Last time you sent one more zip file including the plugin and we uploaded both. Is that feature is added in the latest version or not.
