>>105960556This. Literally the same happened to me.
A couple of weeks ago I saw my uncle deleting photos taken at parties with his friends. I asked him why and he said that his iPhone was full that he will need some storage for when he'll go on vacation. I got suspicious because he got the new iPhone this Easter and seems odd that in just a few months is already full. I looked into the notification and it said that iCloud backup cannot be uploaded because iCloud storage is full. His local storage was just 50 GB out of 256.
I said to disable cloud backups and he told me: ยซI ain't disabling shitยป. He kept deleting photos after that.
