Unable to correct the wrong HW assignment in the Portal.

It is impossible to change the homework assignment if students have already started working on it but there is a workaround.
Create a new assignment with assignment type Classwork with the Assignment Name "Homework ##" and with the correct HW ## in the Problems List.

Example:

Publish the new assignment and send an email to your students explaining that the correct Homework can be found in the Student Portal under Classworks under the name
Lesson ##. Classwork Homework ##.
