I cant back up or toggle on icloud photos
So recently I’ve been not able to togle on my icloud photos or back up beacuse it says my storage is full. In m storage it says that my photos are using 2 GB of storage but in icloud it says that photos are using 2,5GB, my iPhone hasn’t been backed up in a while is it possible that photos from my previous iPhones are on but i cant see them?
