Do screenshots of the NFT tickets work?

There is no point in screenshots!

We know you're excited, but we can't accept ticket scans through any other system than the Relic Wallet App. Copies of barcodes presented through third-party applications, screenshots, or printouts will not be accepted at the venue.

Printed PDF tickets will be accepted if the organizer chooses to allow PDF tickets.  In this case, the customer will be allowed to choose either to have an NFT digital ticket or a PDF ticket.  The PDF ticket can only be used once, same as the digital ticket.
