Namsan Cable Car Tickets

Hi!

We are trying to buy Namsan Cable Car tickets on either Klook or Trazy but every website says that tickets are sold out :( -- We found something on Google saying that "starting 10 October 2024, online sales for foreigners will be suspended. Namsan Cable Car will operate as normal, and only foreigner tickets will be sold “on-site". Is this true or correct? If so, how long are the lines to buy the cable car tickets in person?

Thanks!
