iCloud storage

Hi, I have quite the issue with iCloud. It says that there is over 800 MB of additional Data that I can’t seem to find, let alone delete. How do I remove that and why can’t I see what data that is?
Thanks

Hello

Thank you for your letter. Is it convenient for you to upload some screenshots or videos to describe it in detail? So I can help you better.

Hello,
I don’t understand how that would help, since you can’t see the 800+MB or where they are located. It only says that there is an additional 800 MB taken by this application. What would happen if I completely delete everything after making a backup?
Kind regards

Hello

Hello, icloud data belongs to system cloud backup and is not controlled by MarginNote.
