Ipad wont upload pictures to iCloud
I have an 12.5GB iPad that I only use to take pictures and videos for family events. My ipad is currently overstored with no avaiable space left, so I decided to convert to iCloud. I purchased a 200GB plan to store all my photos and information into, however, I'm not sure what I'm doing wrong because my iPad is still full and my iCloud storage is still empty. My iCloud has all of my data except for Photo Data. I tried to backup multiple times and it still won't gather any of my photo data. I have 423 photos and 41 Videos. I know for sure 200GB is enough to store that and more. under the iCloud category for Photos, my settings are "Automatically upload and store your entire library in iCloud to access photos and videos from all your devices" with Optimize iPad Storage selected along with Upload to My Photo Steam and iCloud Photo Sharing. My iCloud has 199GB of storage, however, under my Storage category, it says my total storage is 0 bytes with Available 3.9 GB. Please help me it is soo fustrating thinking that I've wasted money or can't do anything but buy a new iPad
