Whatsapp backup not enough iphone storage
Hello,
I have an Iphone 14 Pro Max 256GB, I'm trying to create a whatsapp backup of 39.99GB to my icloud where I currently have over 200GB of free space available, but I'm getting the following error "Not enough iphone storage, free up 39.38GB of storage space on your iphone to back up your charts"
This is confusing and frustrating, why do I need the free space on my phone when the backup is going straight to iCloud? even I free up the space required, I will still get the same error. Is there anything I can do please?
Many thanks
