I have both sync this Ipad and sync this Iphone but I only have 3k photos in my Icloud yet i have 100k photos in my photos app. How do I get all of those over to my phone? My Ipad storage is completely full and I cannot share any photos to my Iphone because it says low disk space. All of my apps only take up little to no space and I cant delete anything to make my storage clear up even a little. Well, except my drawing app procreate which does take up a whopping 17GB of space. But I cant even delete that because It takes so much storage to store it in my files, aprox 2mb EACH drawing which is just storage I dont have to store it. I dont want to lose any of my drawings but I simply dont have any way I can think of to move everything over to my Iphone. My Ipad version is still on 16.3.1. With only 64GB full. If anyone has any solution that would help so much.
