Britbox switching to ITVX on 30th of April
Sony customers that are using the Britbox application on their Sony TV will have to switch to ITVX from April 30th onwards, as the app will become unavailable from that moment onwards. The app will be removed automatically. If you still wish to watch BritBox content you will need to do so through ITVX Premium on your device.
