I'm trying to create a WhatsApp backup of 32.99 GB to my iCloud where I currently have over 100 GB of free space available, but I'm getting the following error "Not enough iPhone storage". This is confusing and frustrating, why do I need the free space on my phone when the backup is going straight to iCloud? I will still get the same error. Is there anything I can do, please?
