You can delete files in recent uploads view in Office Lens, but it does not mean you can delete the file in OneDrive. Is your suggestion the ability to delete files in OneDrive from Office Lens??

On iOS my Office Lens is using over 2GB data. It’s taking ‘ages’ to delete each file one-by-one from iPhone.
All my are sent to OneDrive, I don’t need or want them on the iPhone too. In fact, they’re on the iPhone but in the much better OneDrive app.
PS: Lens is great, this is my main issue.
