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