My note is split in two pages.

Or even more! It's completely fine, and not a problem.

If you are preparing the hypertags in the PDF, you can place the same hypertag on the next page using the same URL. The engine will then detect both and the information will be gathered under the same element.

If you are using TextSearch as block tagging method, the frame that defines the text to be recognized (Hyperlinked with area://text) combined with your script (Excel template) will read and locate the information that needs to be tagged regardless of its placement in two or more pages.
