Thunderbird 23 Limited Express Kanazawa: Cancelled or Reduced

Hello - we are trying to plan our transportation from Kyoto to Shiga Kogen. In my mapping, it notes that the Thunderbird 23Limited ExpressKanazawa is reduced. How can I learn more about what that means for us? Are we best to avoid? In searching, it confirms that things have resumed but are limited. We want to plan ahead if possible.

Thanks!
