Worksheets deletion

I need to deletion some worksheets of my students but the functions Edit or Removal are not working and no way to delete than one worksheet at the same time.

I am really avoiding use the Liverworksheet linking with my students and I am thinking to abandon it at all cancelling my account.

The platform is getting bad to work the last years. Don't you want to be pleasant to your users?

I hope you could solve this problems till the end of May.

Waiting for your solution.
