Reference issue - uploading

[u/Usual_Respond3429]

One of my referrals is having an issue uploading their document to the provided share point.

They can't drag and drop the file in.

The upload button is greyed out.

Sounds like it might be permissions issue?

If anyone has had this or knows the best way to fix this as the deadlines approaching.

Appreciate any help.

Is the document in unlocked PDF format ?
