Concert ticket help?

I bought my tickets for Mitski through seat geek a few months back. I randomly received a email that the reseller canceled my tickets. I received a full refund, but I still have access to my tickets. Usually when buying off seat geek the tickets go right to the app, but these tickets were sent to me from a link. I still have the link and when clicking on it still have full access to the tickets. I don’t know if there invalid now? Or if I could still use them? || I was thinking it could be possible the reseller canceled my order to resell my tickets for a higher price. Idk if that means people will have access to these tickets as well as me and could potentially be scammed or what? Plus with the spike increase in price I can’t afford to buy new tickets.
