iCloud backup negative size
Hi,
I have made an iCloud backup previously for my iPhone XS and it used my iCloud storage accordingly. However I backed up yesterday and it seems to have not taken any of my iCloud available storage.
Not only this but if I go into manage storage and go down to backups it says -24Gb.
Can I rest easy in that the backup is fine or is something wrong here?
iPhone XS, iOS 12
