QR-code / ticket should go old

Hi!

I ran to feature/bug/real-life problem.

Tickets does not go old, in such way when their do-date is (let’s say 9.9.2019 at 5pm), the ticket is usable endlessly – which makes it use more time at door to check the ticket is to right show/time. Ticket should/could be so it has gone OLD/unusable after XX amount of time after show has started.

Is there way to make ticket go old after sum-amount-of-time after the show date-time?

Or could have it as new feature in future release, where everyone can set their own GO-OLD-time after show starting time?

Thanks in advance.
