How can I recover missing iCloud storage space? I have an iCloud account with the free 5GB storage, which I want to use for backups.

I have a strange situation where my iCloud is showing as having only 2.2GB space available:





But isn't showing what is using up the space.

I have previously used it for backups of various devices, but these aren't showing.

How can I recover my lost space?
I ended up phoning up iCloud support, and they were similarly baffled. They tried a load of things (none of which worked), and eventually they then asked me to delete the WhatsApp Documents &amp; Data storage. Despite it saying that only 350MB was being used by WhatsApp, deleting this immediately freed up around 2.8GB (350MB plus the ~2.5GB of "lost" space) in iCloud.
