iPhone 7+ Low Memory randomly
I store practically everything in iCloud and have my photos set to optimize storage. On my iPad, it shows Photos are using 4.46 GB of memory but on my iPhone it is now showing Photos using 106.99 GB (both use the same iCloud account so all photos are on both devices). I have iCloud Photo Library & Optimize iPhone storage checked under photos. I also have Upload to My Photo Stream turned off.
Why would this randomly happen and how do I fix it?
