My question is to do with the two different results for photos and videos on both the device Storage and on iCloud? Under Settings/General/Storage & iCloud Usage:- the Storage/Manage Storage informs me in my Photo Library I have used 20.4GB and under my Photo Stream 2.1MB. Under the same but for iCloud the Manage Storage informs me I have 19.3GB of Photos and Videos. My question being:- Whilst I understand my iCloud storage and that all the photos, videos, albums etc are shown on all my devices my confusion lays with the Storage of Photos and Videos on the device. i.e. On the device storages of my two main devices my Phone says I have used 20.4GB but on my iPad Pro it says 18.3GB. Obviously both devices reflect the exact same for iCloud Photo storage. If these two devices show different results for photo storage where exactly are they stored and why is there a difference in size between the device storage and iCloud storage? Hoping someone can shed some info, thanks.
