If you do screenshot your tickets within the app then a warning message will be displayed. This is to deter people from duplicating tickets multiple times.
Please be aware that your ticket(s) won't be cancelled if you do screenshot them within the app but unauthorised duplication of tickets may result in them being cancelled with no refund. This also applies if we spot them being resold on another website.
If you do need to send tickets to someone else then please head here for more information on how to do this.
