If RSS Feeds are not working in Chrome firstly check if they are working in Firefox. If they are not then it could be an issue with the feed itself or there is no internet connectivity on the Optymyse Server.
If however the feed is working fine in Firefox or Edge but just not in Chrome you will need to install a RSS feed extension for the browser.
Click the link below or paste into Chrome to install the extension:
Once the extension is installed refresh the display/page you are trying to view the RSS feed on and it should work.
If not, close the browser the open it and load the display.
