What exactly uses the iCloud storage. Is it any photos or videos you have on your phone and emails? Does the iCloud sharing use iCloud space? Reason I ask is on my phone it says my icloud starage is full yet I can still receive photos through the iCloud sharing. I’m wondering if I will need to open more iCloud accounts to save more photos and videos as I refuse to pay the monthly rate to get more storage. If it was one off cost then maybe but not a monthly cost.
