Rangers TV works on modern desktops, smartphones and tablets with updated browsers, If you haven't updated your browser in some time please do so.
Browser update: https://updatemybrowser.org/
If you are using a tablet/mobile device, please try downloading the official app instead. This is available through the app store and google play store.
I would also download Google Chrome and use it as your preferred browser if not already using.
