iCloud Photo Library "Preparing Items"
I've uploaded my entire photo library (about 25k photos) to iCloud Photos library. (I did this a few months ago when it exited beta on OS X)
Today I noticed that my iPhone is "Preparing [25k] Items" (visible in Photos app and in Settings / Photos and Camera / iCloud Photo Library)
My settings are set to "Optimize iPhone Storage"
What is going on? Is my iPhone trying to re-upload all of these photos?!?
I noticed that my battery has been draining very fast and the phone is quite warm. No other apps are running.
Anyone else seeing this behavior?
