Yes, if you're using Discovery+ via Sky Q and you see a QR code on the screen while attempting to watch a program, you can scan the QR code with your mobile device. This often allows you to stream the content onto your device or log in to the app for a more personalized experience. Just follow the prompts that appear after scanning the QR code. However, make sure that you have a valid subscription for the content you're trying to access.
