This happens when one or more students redeem an incorrect token, which gives them access to different material than the rest of the class.
This difference in redeemed products also affects the teacher, as the platform displays content related to the tokens the students have redeemed.
Recommendation: It is important that the teacher verifies the class agreements beforehand (i.e., the corresponding product or token) to ensure that all students have the same material. This guarantees a consistent experience and avoids confusion or restrictions when working with specific activities or assignments.
