Title is basically my question. I went to buy my Shinkansen ticket for this AM (Hikari, Toyohashi -> Tokyo) late last night. Usually the app doesn’t let me in the app at 2 AM but that’s when I bought it. Is there certain systems like IC binding ones that don’t work at that hour? Is it because I got a ticket so late? I’ve bought tickets literally 5 minutes from my train’s station and never seen the QR option get forced. I almost missed my train but thankfully staff saved me and expedited me.
If somebody knows some information regarding this or other weird quirks for the Shinkansen or IC systems, I’d be interested to hear.
