As per the S&I Official Communication released on March 25, 2024:

A new study plan has been created in the Home section of the Gospel Library app to assist youth as they study the Book of Mormon this year. The plan contains the required Book of Mormon Seminary Readings for 2024 and will assist students with tracking their progress as they study the Book of Mormon. On your mobile device, consider demonstrating to students how they can easily find, start, and track their progress with the plan, as shown below. 

This tool is meant to help students in their studies of the Book of Mormon, but currently students marking readings in the Gospel Library App does not sync to mySeminary or WISE. To receive credit for their reading, students are still required to mark their reading in mySeminary.
