If an event is postponed, what happens if I don't request a refund?

Nothing bad, don't worry. If you don't do anything within the 30-day window, your ticket simply stays valid for the new date, exactly as if you'd actively confirmed you're coming.

The 30 days is really there for the people who can't make the new date, giving them a genuine window to get a refund. If you're planning to attend, there's nothing you need to click or confirm at all.

One thing worth knowing: once that 30-day window passes, the refund option for this specific postponement closes. So if you're on the fence about whether you can make the new date, it's worth deciding before the deadline rather than after.
