Problem UNSOLVED (Workbook)

To whom it may concern,

I decided to make public my problem so that MAYBE someone from the staff can solve it...

I have already emailed them during 10 days... The problem is one of the students told me she can not open the worksheets of his workbook. He sees them but it does not open to complete them.

Also, the teacher (me!) can't see her answers but yes her marks! 

I have sent them pictures and users/passwords for them to check and we still don't have a response. 

We (teacher, Headmistress, student and parents) are really concern and dissapointed about the lack of attention and problem solving from the platform. Specially because every detail affects our kids and their lesrning process, it is quite important!!!!

We hope making this visible get us a promp solution, otherwise our student will continue falling behind in her tasks until we leave Liveworksheets for ever...
