You should always read carefully the instructions stated in the ticket details and in the confirmation email, as sometimes extra steps are needed (e.g. calling to confirm reservation, etc)
In some cases, you only need to show the ticket to the venue staff in order to enjoy the experience. However, it is quite common that you need to validate the ticket as well.
You must only validate your ticket once at the place of the experience, with the venue staff. To validate it, go to the "Tickets" section on your profile and select the ticket. Then, click on "Validate tickets" at the bottom. Please note that this option will appear just one hour prior to the plan start time to avoid validations by mistake.
By doing this, a new screen is presented. Simply write a letter V with your finger.
