On most e-ink devices you will trigger the hyperlinks on the page of your planner or notebook with your finger, not your pen/stylus.
Simply tap with your finger on the area of the page that is hyperlinked, and this should trigger the link to take you to the destination page. You can see additional details on this page: Getting Started with eInk Tablets
Typically, the first couple pages of your planner/notebook template will include some tips and details around the location of the hyperlinks on the page.
Feel free to send us a message if you need help with a specific template.
