Hi,
I'm Nik, an independent advisor here to assist you with this.
To help you further, could you please help me with more details?
- May I know that if you have shared the document by uploading it to your OneDrive and share the link with pupils?
- Have you uploaded the assignment document directly to the "Add a resource" section?
- Also, do you see this issue with some pupils that have been added to class recently or all the pupils?
Please let me know the source of document location, and I will look at things for you.
Regards
Nik
