I started using iCloud Photos recently and love it. I have photos syncing on my iPhone(16gb), my MacBook Pro(240gb), and in the cloud of course.
My issue is that I have 12 photos on my phone that are not syncing to the cloud. I am on WiFi, the phone is fully charged, and they are just stuck on my phone. I've looked on my MBP and they aren't there. I've looked on the iCloud via the web app and they aren't there.
When I go on my phone to iCloud / Photos, the message says "Low Disk Space - Uploading 12 Photos" I have 163mb of free space on my phone, and 125gb of free space in iCloud.
My Question is, is there a way that I can manually clear the cache of photos that have downloaded to my phone. I have 750mb used in the "Photos & Camera" application, and I am sure a good chunk of that is from me browsing old photos which are temporarily downloaded to the phone for viewing. When I typically look at my library on my phone, the photos start off as empty white squares and that's okay. I've looked at a bunch, and it downloads thumbnails and lower res images of the files. Can I clear these caches to free up some space?
Also, I've read that the system requires at least 300mb of free space on your phone to upload photos to the cloud. Is this true? I can't see why this would be a requirement.
